wrong debit order date and incorrect charges

the month of april they debited my account on the wrong date 19 instead of the 20th, the account charged me bank charges, and later the debit order went again on the 26th without my consent and bounced again which caused charges again. finally went month end and they got money. and after a month they suspended my subscription and when i went to telkom store they told me i have to pay extra R201 for unpaid debit order, like really now? i then explained what happed and they refered me to call centre for dispute

i then called and talked to a lady called Aphelele who asked me to send statement as proof, which i highlighted and sent it to her early this month, and no reply until now. all i can say is i am really disappointed with your service, i really thought i can rely on you since your prices are reasonable for sim data that i have used on my wifi. please assist me so that i can reconnect. ***
