Poor service from WeBuyCars and customer care for refund dispute

I purchased a vehicle from We Buy Cars Riverhouse Durban through their online auction .The dekhra report didn’t state that the vehicle had severe hail damage . I raised a concern but before my concern was rectified the branch cancelled the deal without my knowledge and forfeited my deposit of R4000. I was then allocated a case manager who made me sign An agreement on 2024-09-16 to get my R4000 deposit back which would have been paid into my account within 3 days and up till now I haven’t received it . I then had a Deposit in my account which I was using to purchase other vehicles from WeBuyCars of R4000 aswell.I did not win any bids and requested for my deposit to be sent back into my bank account(this deposit is independent from my dispute ). WebuyCars online sales team and the case manager (dispute refund)then sent me the same payment notification with the same reference of R4000. I contacted the case manager stating that the payment notification he sent me was incorrect and I had not received the dispute refund amount of R4000 and the payment notification that he had sent is from my deposit I used to bid for other vehicles which is also R4000 .I tried contacting the case manager via emails and telephonic calls for the last two weeks to request my refund and rectify their mistake but the call centre stated he was busy and up till date he didn’t reply to my emails or contact me back . I am very disappointed in the service I’m getting as I’m a regular buyer from WeBuyCars .
