Rcs - terrible service !!!

I am so sick of the poor service of rcs . 2 months ago I paid my account instore on date and on the 14th they emailed me claiming I didn’t pay - meanwhile they just hadn’t allocated it! Now I paid via eft as I normally do and have been doing for years on 30th sept. I used the card on the 1st oct and got a message saying my account was in arrears and no payment received and now additional fees will be due on my next payment. Immediately called and emailed on the first - even sent pop through . Still nothing . Called again today around 10ish and the agent put me on hold to check and said she would call me back if the call cut as she was escalating . True as Bob the call cut - it’s now about 8 hours later and still no call back and still payment not allocated !!! TVs is getting terrible - I expect someone to call me with this resolved !!
