Credit refund issue

So currently i am trying to get my credit refunded and every time i contact customer service they say all they can do is raise a complaint and that they was either a technical issue or they have no record of the previous issue being discussed... I now am told over a week later of another wait that a cheque has been sent out even tho i was told and requested a refund to my bank account and from other countless complaints on this forum and reddit i can see that it likely not been sent. I want my money back and i am sick of wasting my time with customer service who are either incompetent or being told to drag it out in the hope customer just forget about the money.

Below is a email sent after me previous conversation with customer service on the 08/10/25

Customer account number: [REMOVED]
Complaint reference: C-0810256391
