PLEASE HELP! EXTREMELY UNHAPPY WITH BAD SERVICE

Good day, I have been mailing and calling Edcon, but I just get the run around every month. I sent a mail in June 2018 with proof of payment, then again in July 2018 and then again in Aug 2018. All I get is an electronic auto reply saying they acknowledge my email however, I am not getting any feedback or a letter stating that this account is paid up? Could someone please look into this account and come back with a positive response. This is extremely frustrating when I am trying to work with a creditor but the creditor treats their customers with disrespect.
