Queens Park /RCS accounts

I paid my account in-store on the 3rd of March 2019. RCS claimed not to have received my payment. They called me twice a week, (which carries cost by the way) they send me sms's 2-3 times a week, which also carries costs. Every time i call them on my side "i guess it doesn't carry costs according to them" Until this day 5 June 2019 i still receive messages that i have not paid and i have emailed proof of payment 3 times. The message i received today 5 June indicate that they are handing my account over to ITC, since i refuse to honor my payment. What i want to know from them who's fault is it? I paid in store i have my till slip. Head office did not receive my payment. In the meantime the account they claim i did not paid is busy accumulating extra charges. I demand they solve this matter as soon as possible since i am paying to call them too.

i will appreciate Hello Peter to intervene in this matter please. My AR number with them is AR 782025
