non-customer centric behaviour

I'm lodging the following complaint to notify you of the following non-customer centric behaviours from your organization;- <br> <br> -Abusive smses and phone calls claiming that my account is in arrears, this is unacceptable!<br> -I never receive statements of the account with payments that I make, this is not in line with NCA and consumer protection act, I will be taking it further<br> -I've never received any positive assistance from either of your branches, namely Eastgate and Bedford centre even after producing a receipt of payment made at that specific outlet (my last payment of R1000.00 was made on the 25th of February)<br> <br>
