After 3 months of escalating a request NO feedback

I have had two data ****les with Vodacom for nearly 10 years now. In that time, I haven't once been offered an upgrade on either ****les, and they are very outdated and the signal is bad. When I called to find out if I could get an upgrade on the ****les THREE months ago, the call centre operator told me that I was offered an upgrade and I declined. I asked them to find the proof of this, and they escalated the request to management. NO feedback received. I have called four times now (escalated each time), and I have emailed three times. <br> I cancelled the ****les a month ago (to expire on the 1st of November) and was told I had to pay a cancellation fee, which I explained I wasn't happy about because of the above. Again, four emails and four phone calls, with NO feedback. The lines are still active, and I am being charged. I am unable to use both, as they were both ****** and suspended two months ago. <br> At the end of my rope now. <br> And to top it off, I just requested my upgrade, and they have decided to charge me a handset fee this year, when I wasn't charged for it with my last upgrade. So my contract has gone UP by R300 per month<br> Two references: ***, A1/XDAR/2M42CY
