*****ulent billing for September and October. I wamt my money back and cancel my month to month data

Salome Govender ***I have been debit more than my premium. I took a month to month data but for the past 2 months i have been billed more last month R900 andthis month R700. I did call last month and also took it to Hello Peter but the consultant did not be of much help at Telkom. Please i want my money back and cancel everthing i have with you. I was happy with the benefit until you started billing me more that i don't know about.. Please please give me my money back for Seltember and October.
