OZOW payment NOT REFLECTING ON BWH ACCOUNT

Very very unhappy. Made a payment on my RCS BWH account on 4 April 2023. I noticed that on my account the payment has not reflected and started forwarding the payment to *** Few days later got a letter of demand for outstanding payment for double my installment. I forwarded the proof of payment again. Get a call from RCS collect for non payment on my account. I forward the proof of payment to rcs collect where they respond and say thank you and they forwarded the proof of payment to the relevant department. Few days later get another call from rcs collect say story, apologies for the inconvience but can I please get a proof of payment from the bamk where it states that the money has been paid from my account and into which rcs account the money has been paid into. I went to the bank and they gave me a proof of payment that shows the money was paid from my bank account into rcs bwh account. Forward this proof of payment to payments department and to rcs collect. Next day get a call and sms for non payment on account. I have made use of the OZOW payment method from RCS. I have forwarded a few messages to rcscollect, a 8 emails to payments and a few messages to complaints. All still no correction on my account??? I phoned on the 08 May and spoke to a consultant who then told me that the payments department NEVER received my proof of payment, but can I please forward the proof of payment again while she is holding on the line to confirm that the payment was received. Done this and she confirmed that the payments department has received the proof of payment and they apologise for the incovinience but my account will be rectified within 24-48 hours. Today is the 13 May and still no payment reflecting on my account???????????? WHY IS THIS PAYMENT METHOD OFFERED IF THE PAYMENT CAN NOT BE LINKED TO AN ACCOUNT???? WHY HAS MY PAYMENT NOT BEEN RECTIFIED/REFLECTED ON MY ACCOUNT????
