Store account doesn't reflect my payment

On the 27th november 2020 i made a payment for my store account on the mrp app like i usually do for the past 3 years, anyways after i made the payment online i never received a reference number which i found weird, so i checked my bank statement and the money went off my bank account, i called mrp and they advised me to email my bank statements which i did over 15 times to different email addresses that i was given by the customer care people however i still have no resolution or feedback, it has been 3 months now fighting about R160 . i am closing this account.
