Poor Customer service

To whom it may concern. I have experienced the most unpleasant service with Vodacom and my issue is still not resolved and all is said to me is that there is nothing further that Vodacom can do for me. I'm trying to get answers since the 11 October 2019 with no success. All I must hear is about Vodacom's inhouse problems which has nothing to do with me as a client. I cancelled my Wifi a month ago thinking that my Fibre should be installed for the latest in November, but they only want to install on 22 January 2020. I'm now currently purchasing Data which is costing me a fortune for the past month. The sales consultant that sold me this Fibre contract told me that once I'm approved, It will be in a matter of days for my installation to be activate without me doing anything and It's almost three months now since sold to me. If this issue is not resolved, I am escalating this matter. Thanks. Brent
