RCS Wrongly debitied the Wrong bank account and cant fix their mistake

SO where to begin. I have never truly had issues with RCS. Now initially this was not their fault. I changed banks from Standard bank to FNB. This is where the issue started. Not all of my debit orders were carried over correctly. However after having to bay some payments via EFT and many calls and emails. All was well with the world.

This month however they attempted to deduct their monthly payment from my Standard bank account which didn't work. a few hours later (maybe 2 at most) i received a notification on my FNB app that a new debit order for RCS-Game account has been established. I chucked it up to an accounting error and let it be. Two days later i get an SMS and email stating i need to now pay 2 months worth of payments immediately to avoid being handed over to the collections department and to avoid my credit score being affected.

Naturally being very confused i called the number supp****. I explained the issue to the agent. However it seems that she either didn't understand what i was saying or i wasn't clear. She stated that i had not updated my banking details with them for my Game account. However if this was the case HOW did they deduct payment for may?

She then continued to say it was a once off debit order and that, that was canceled. However i didn't cancel it, request it to be canceled nor did i receive a cancelation notice. Which in its own right is laughable because if i wanted to update my banking details i need to supply a copy of my ID, banking statements a bank approved letter, and all my updated details. But they can cancel a debit order without my say so?

Lets continue. The agent explained that i had a Debi-check mandate with Standard bank for my RCS-Game account. I would have to cancel that with the bank. Then inform RCS of the cancelation. Then pay the outstanding amount, then go to Game and arrange with them for a new debit order and then call rcs to get a new Debi-check mandate for my FNB account. This seems excessively like a runaround just to change banking details.

Okay, frustrated beyond word. I give in and tell the rep i will do all of that today. Okay after a struggle to get ahold of an Standard bank representative and being called by another RCS agent and having to explain the whole thing again.. I finally get in touch with Standard bank. Then inform me however there is NO DEBICHECK-MANDAE for ANY RCS account. Not the Game Store card nor the normal RCS account. Which is weird because the RCS agent explicitly said i had one. I actually have screenshots for all the Debi-check mandates now after getting some assistance from standard bank.

Now i get another e-mail stating i need to make payment arrangements and that i will be handed over to the collections department...for 1 payment. Which was June's payment. They note there was a payment made in may and i only owe June but now i must pay for June and July for some reason i cannot fathom.

ALLLLLLL of this because someone messed up and now it has become my problem. I will be sending them the required banking details for my FNB account AGAIN after this post. I don't know why since they were able to perfectly deduct money via debit order last month. i hate to complain. I dislike this very much. However they are costing me money and my pretty good credit rating of which i am proud of is being affected because of their negligence. Unacceptable. I expect to hear from a RCS representative to resolve this issue and hopefully i can keep a cool head with this person as it has been unbelievably difficult so far.
