Vodacom Billing Enquiry still not sorted!

I'm extremely annoyed as I have not heard from Vodacom for a week after my billing query was supposedly 'escalated' for investigation.

I tried to cancel my contract after being billed ridiculously for a couple of months. The retention department offered me a special deal to keep me with Vodacom: the Flexi UChoose 120 for R70 per month with 1GB of data. Pretty good deal so I agreed. He mentioned that this deal is only available through the the retention program. The guy told me it would be activated 1st if October. Well I have had 0 balances for the entire month.

I called to enquire on 5th October. The 1st guy checked my account and saw that my airtime had been allocated but not the data. And so all my airtime had been used for internet since I thought I had data. After chatting to 3 people I eventually heard what I wanted to hear which was that they would investigate the deal which I assume would be to listen to the recorded phone call promising me the gig of data. And that they would refund me the R120 airtime that was used up in a couple of days!

I still have not heard back and am having to recharge my airtime continuously while wasting it with terrible out of bundle charges.

I want to hear from them ASAP and I want my contract fixed or cancelled for good.
