Disgusting service

On the 10 November 2018, I made a payment R1312 to my Woolworths store card, to date it has not been allocated to my account, I was threatened to be handed over, I sent through a proof of payment as requested, then I was asked to send a bank statement, it still has not been resolved, the payment was made via the company listing on the banking system so the details are preloaded by the bank and I put in the ref as normal, it is now 4 months later and Woolworths has not even gotten back to me regarding my R1312 made to them, if this cant be resolved I need my money refunded to my bank details on request, this is absolutely disgusting service
