Account **********ly upgraded without concent and query marked as resolved even though I'm still being sent a bill

A month ago I submitted a claim with the ***** department regarding vodacom my account which had been **********ly upgraded without my concent or signature. Vodacom rep**** communicating that they had cancelled my account as per my request. I have recently received a bill amounting to over R9000 on the same account for August! How can this be? This is shocking. How many times must I log the same call with Vodacom before they resolve this issue. The level of service delivery from Vodacom is not satisfactory. The sad part is that my query was logged as "resolved".
