Vodacom-data usage, account department, investigations and bad service

<p>In 2014 I upgraded my internet contract to a wifi router at clear water mall vodacom. I requested that a soft black be added to the account in the event that the data given per contract is depleted. I was informed this can only be done once I exceed 100mb over my data cap. Although i was not happy with this I asked it to be app**** to my account and was assured that it was added to the system. Two years later An amount of R1839 was deducted from my account. I reversed the amount, went to clear water mall vodacom in the first week of December and was informed they could not give me any info other than I owe money. Thereafter I had to call accounts department and log and investigation that would take 7 - 14 days. I was told to also request an itemised billing statement that would tell me exactly how much data was spend on which website and this would be for my account at R23 odd rand. To date 04/01/2017 I have not received a statement or feedback from vodacom. I want to know where this account comes from as I never exceed my data usage. If it was exceeded why was the soft block not activated? Why does it take so long for such a big company to give feedback to their customers and assist with queries.<br />I want my account to be corrected and recalculated to my normal monthly payment and if there is additional data usage it should be calculated for no more than 100mb exceeding my normal data cap. I was guaranteed that this was added to my account. </p>
