WRONG INVOICE

Cellno: ***: Vodacom bill me for a handset I send back. The device was under warranty and the terms and conditions were not adhere to by Vodacom. There was an agreement that the upgrade is going to be cancelled and void. Vodacom promise to issued a credit note for the device only. A credit note was issued for R557.00 on 3 November 2015. The complaint is that Vodacom charge/invoice me the amount of R2498.98 for a handset they pick up and booked in back on their stock. Never ever was it said they going to bill me. But anyhow how can they bill me for a device I send back on their request. Another mistake on my account cell no.***, they convert my existing Flexi 100 to everyday off peak 120. This is also incorrect. I never requested this change.My subscription was R210.00 and now they bill me for R235.00. Please help solve this matter. My ID no: ***. Account with Vodacom Is:I***-1<br>
