VODACOM ACCOUNTS

Good day Team Seems like I'm getting no assistance with my contracts or invoicing to be billed correctly but payment is done on time on every invoice Last month I called in and cancelled *** as I advised the consultant that I will not be requiring this number, I called again and was told the contract was not cancelled it will be investigated and Vodacom will revert back. if it's your fault there will be a rebate but up till today no response. Secondly, I took our insurance but every month I'm getting charged more than once and in different amounts which are now ridiculous Before the account will be paid this month I want my invoice to read correctly ***Why is this amount so high for R300 this is not what was agreed for the data package? *** I'm being billed so much and only for airtime? Please I need this also to be resolved I feel communication on the phone is not correctly actioned
