Useless support and unfair account restriction

Very disappointed with Sixty60. My account has been restricted from submitting credit requests because I have apparently made "too many claims", yet the claims were for genuine issues such as damaged, expired, missing or incorrect items, and I can provide evidence where required. I formally complained on 25 September and was promised feedback within 24–48 hours. It is now 5 October and I still have no proper explanation. I am simply told the matter is with their Credit and ***** Team. My biggest issue is simple: I pay for a delivery service. If Sixty60 delivers damaged or expired goods and blocks the in-app credit option, how exactly am I supposed to resolve it? I am not driving to a store to fix a problem caused by a delivery service I paid for. Email support clearly does not resolve anything either. Absolutely useless customer service and no real answers. If Sixty60 wants more detail, they are welcome to contact me regarding Ticket ***, although based on my experience so far, I honestly doubt they will.
