Incorrect Billing

Hi. Last November, on the 25th, I believe I spoke to Bavna, not sure of the spelling, to sign up for an extension on my *** number. Realised over the weekend that I made a mistake. I barely use my 072 number, it was pointless to upgrade. I did not take long & the next Monday, on the 28th, I called back to cancel. This is the thing about Vodacom, they will not allow you to cancel freely, always asking questions about why you want to cancel & that they have better deals etc. If you look at my call history regarding this specific issue & listen to calls, I spoke to a number of people, I recall speaking to Juventus, Nothando about this cancellation. I was promised a credit back to my account but I see this has not happened. As it stands, I still have 3 active contracts with Vodacom which in fact it is supposed to be 2, my primary number, the 082 & my WiFi one, the 072. If you can check, I requested more data on the 082 instead of the 072 number which would have made my life easier. Am paying a bit too much on 3 contracts. Can someone please look into this? Thanks.
