Pathetic Service Yet Again !!!

On the 4th of June I communicated contracts/renewals with Vodacom. The lady I spoke to (which was very helpful and friendly I must say), assisted me and after actually wanting to cancel some contracts I did agree to sign up again at discounted rates. However a month ago I phoned Vodacom to query my balance seeing that it was substantially higher than usual. I was informed that two contracts that have been renewed totals that of R191-00 each. I was truly and utterly shocked and asked the consultant at the time to kindly email me the invoices for all my contracts, received six in total which was duplicates of the account already received. I then contacted Vodacom yet again to discuss the matter and requested the call recording. Two weeks later, I still did not receive any feedback from Vodacom. When I decided to follow up yet again last week, I was told by the agent that a request was never logged to request the call recording. I cannot understand why I always have to struggle with Vodacom. I know for a fact I did not agree to R191 contracts seeing that I do have Vodacom WIFI. Further, when the lady calculated my new discounted billings, it was far less than I am suddenly paying now. Can I please have the call recording in order to finalize this matter. Would definitely not advise any person to make use of this service provided - all my previous Hello Peter complaints also refers :-(
