Horrible Service Ever!!! Disgusting service actually.

Made EFT payment on the 26th of March 2020 and emailed through of payment on 6th of April 2020, up until today the payment hasn't been allocated. I have been to Woolworths branch thrice and I had to resent the proof of payment but no action has been taken. I had phoned the call centre plenty times and payment has not been allocated up until today. Last month (May) I received my credit report and my credit scores has dropped drastically and reason for that is due Woolworths failing to allocate payment on their side. Also I keep on receiving SMS requesting for payment.
