RCS horrible service

I wrote review earlier. However I have to update the bad experience. I had an issue 2 month ago when my pick and pay(RCS) facility had problems with their online"self service App" . I did pay my monthly updated payment into RCS account in time(after trying to use the self service payment option) to no avail. I used then my eft option. As reference I used my newly issued store account card given by my Simonstown branch and assured it is registered. However, after eft transfer on 6th I was told RCS they can't find my payment. After endless emails and proof of payment it was found and was assured I don't owe any payment. Today I contacted RCS via phone and found out that RCS put me under debt review regarting the "delayed" payment(on their records, because they could not find it, yet it was paid). So.. Lady on phone said she can't help me, she is asking a supervisor.. Am on hold for ever.. In meanwhile she sends me an email to tell me I must contact " customer friend in Durban" regarding taking me off this unjust "debt review" . Turns out they don't have me registered under my ID and debt review. I sent proof of payment several times and it was accepted by RCS and assured I don't owe anything. Yet I am still appearing on debt review. This is unacceptable and needs to be attended to. But nobody at RCS wants to help!!!!! If all fails I will use my lawyer.
