Lack of customer service

I was notified that I could obtain an upgrade for my Vodacom contract in July- my initial two year contract with this provider commenced in October 2015. I did the "upgrade" telephonically and obtained my new handset a few days later. I would assume that the contract details and costs would remain the same- that there would be a top up in place- as per the original contract- however clearly I was wrong- the terms of the contract changed- without my consent or knowledge. I queried this, only to find that in fact I now have an open line- which is not what I agreed to. I sent an e-mail to customer care querying this on 12/09/2017- and to date this has not been rectified.

I have now spoken to about 4 different people at Vodacom- one suggested putting a limit on the contract- which I would have been okay with- however this required having to be put through to customer care- who on two occasions- failed to answer their phones at all- Brilliant customer service!!!! Initially though- I was told Vodacom would collect my phone from me- for what? and what would you propose I do in the interim without a phone- unbelievable. I then had another call on Friday evening- and we agreed then that the contract would change- it would be more- which again I was okay with- however- firstly the quote was never sent to me- and then when I did receive it, the figures discussed telephonically and what was contained within the quote were two different amounts- how would you expect anyone to sign this- on top of this I receive an e-mail saying the system has a different figure to the quote- All I get is excuses and justifications- I want customer service- I want my issue resolved.

I really regret leaving my previous provider, for what I thought would have been great service- how very wrong I was.
