RCS worst customer service ever!

I paid my Cape Union account in full on the 20th of November. Since then I tried to confirm with them that my account has been updated and tried to close my account. Numerous calls to their call centre was made to no avail. On the 6th of December Andisiwa sent me an email to ask me for my id (while I have attached my proof of payment) - no feedback. Then they started calling me to say my account is in arrears. Five times a day at least. 13 Dec, I was told a team leader would handle the query and locate the payment. No feedback from them at all after that. Yesterday the same Andiswa sent me an email to say thanks for the request to close my account (I sent this email on the 21st of Nov already!) After that she sent me an email regarding a totally different customer's account. Today, when I followed up again - note that this was my 15th call to the call centre, I was told oh yes your balance reflecst as 0 we will see to send you a paid up letter and notification of closing of your account. This is the worst service I have experienced ever!
