On Thursday 18 February I placed a bet with Unibet.co.uk on Forest Green Rovers to beat Newport County at odds of 2.60. The next time I logged back into my Unibet account (after the match had been played) I noticed my account balance was lower than I was expecting. When I checked the bet history I found the following: 18 Feb 2021, 15:32:29 Bet type Full Time: Forest Green Rovers Stake: £238.16 Odds ((2.60)) Status Void Payout £238.16 Result: 0-2 Reason for voiding: Stakes refundedI had not been sent an email to say that my bet was void and I followed the game in the belief that I had a bet on the game and I thought I had won. I went on to the Unibet customer chat and he said: "im afraid these decisions an be made at the discretion of the traders at any point" but I am pretty sure the Gambling Commission does not allow operators to just cancel a bet after it has been placed just because they feel like it and without telling the customer. I will also point out that 2.60 was lower than the odds Forest Green were trading on Betfair (which was 2.70), so the odds were not out of line with other bookies. The agent then told me to write to Unibet's UK support at info-uk@unibetsupport.com and I did so on 23 February and followed up again on 3 March. I have had no response from Unibet - not even an acknowledgement that my email of complaint has been received - and am becoming increasingly worried that no one is even looking at my complaint.In summary, it is not okay to void a bet after it has been placed without warning the customer. You should only be able to void a bet if the odds are clearly wrong (a palpable error) and you need to do that before the event starts AND inform the customer you have done so. In this case, there was no reason to void the bet and it should be paid out as a winner.
