Service sucks

I have 3 queries/complaints

1. I cancelled my 3g Modem (2G data @R99) on 10 October telephonically and noticed that I am still being billed even though the modem no longer works and I have not used the data for more than 2 months. Please credit my account, alternatively re-issue the Vodacom data to my cell phone which I have paid for. Once complete, please cancel as per the initial request. 2. I took out a new top-up contract with Vodacom during the last week in November – my account was recently debited with an amount of R318.00…. I need to know what this was for? Was this for the pro-rata charge on the top up contract? if so, why does my Vodacom app reflect a notification “bill so far: R879.62 if a R318.00 was already debited from my account? 3. I have 2 contracts on my name, is it possible to separate these two on the my Vodacom app? My airtime is at R116,93 and data at 3.94GB – is this for my Vodacom number only ( ********** 606)? 4. On my other number ********** , i received a promotional 1GB data for 24 months and all of a sudden I am being charged R30,58 for the 1GB of data – all of these **** ups have happened ever since I took out the new contract at the Vodacom branch in Pinelands.

Please urgently assist.
