How to Contact Winissimo Customer Support in the UK

If you're a player based in the United Kingdom, there are a few ways in which you can receive help at Winissimo. I put the support team to the test over a week and contacted them via live chat and email regarding bonus and withdrawal matters. Now, let's take a look at the various contact methods.

Support Channel	Availability	Avg. Response Time	Contact Detail
Live Chat	24/7	2–5 minutes	Via website (lobby.winissimo.com)
Email Support	24/7	12–24 hours	customersupport@instantgamesupport.com

SB Suggests: Live chat is your fastest option — I tested it twice and got human support in under 3 minutes each time.

Support Experience – Desktop vs Mobile

I tested Winissimo's support on Chrome (desktop) and Safari (iOS) to see how different or reliable both were. In short, both were dependable, but different:

Live Chat: Both worked perfectly on desktop and mobile. The chat window is accessed through a button in the bottom right on the site.
Chat Logs: All chats get emailed to you for referencing, which is great for tracking issues.
Response Quality: Agents were great at explaining the withdrawal processes and KYC requirements. For instance, when I inquired about a delayed withdrawal from PayPal, the agent was clear on the 1 - 3 day back-end processing times.
Mobile Quirk: The chat button on my iPhone completely vanished even when switching pages (the button reappeared after refreshing the browser).
Evening Hours: While on chat support, I noticed a slight delay (5 - 7 mins) when receiving replies during the typically busiest evening hours (7 - 9 PM BST).
Real Insight: The mobile experience is good but simply refreshing the page will solve any irregularities with the chat button disappearing.

What Can Support Help You With?

You can contact Winissimo’s Customer Support team for help with a range of issues. Based on my experience, here’s what each channel is best for:

Issue	Support Channel to Use
Missing bonus	Live Chat or Email
Withdrawal delay	Live Chat or Email
KYC documentation	Email
Account timeout / RG tools	Email or Live Chat
Game loading issues	Live Chat

For example, I used live chat to resolve a missing £10 free bet bonus, and the agent credited it within minutes after verifying my account.

How to File a Complaint at Winissimo (UK)

If you are dissatisfied with Winissimo for any reason (a bonus, a payment delay, or an account problem), Winissimo has a clear complaints process! I put this process through its paces with a phony bonus issue, here’s how it works.

1
Step 1 - Contact Customer Support First
For your first contact with Winissimo, you will want to reach out to support with live chat or email customersupport@instantgamesupport.com.
In my case, live chat responded to me in under 3 minutes and had a solution to my issue in short order, for just about everything else, this first level of contact should suffice.
2
Step 2 - Make a Formal Complaint via Email
If you have tried informal attempts at resolution, use the email complaints@instantgamesupport.com to formally escalate your issue.
Subject Line: Formal Complaint – [Your Username]
Include the following:
- A clear description of the issue
- Screenshots/evidence (e.g. missing bonus, failed payment)
- Any relevant chat/e-mail correspondence
Winissimo makes a clear commitment to respond to formal complaints within 24 hrs, as part of their obligations under the UKGC social responsibility code provision 6.1.1.2.
3
Step 3 – Escalate to eCOGRA dresses (ADR)
If you haven't received a resolution after 7-10 working days, you can escalate your complaint to eCOGRA, the site's designated Alternative Dispute Resolution (ADR) provider.
You can submit your case at:
https://ecogra.org/products-services/alternative-dispute-resolution
Collect and keep track of all communications, regardless of the medium (i.e., emails, chat transcripts, or supporting documents) to help your case.
Tip: If your funds are stalled, or the bonus terms don’t seem fair, make sure that you have documented communication and correspondence first before escalating the issue to eCOGRA.
