Pathetic Service from Vodacom

I app**** for and received a LTE data deal of which the network coverage and speed was absolutely poor. I lodged a complain, I received a call from Amber Killian who advised the investigated my query and noted the towers in my area are congested and Vodacom will be installing more towers in my area. I requested my LTE data deal to be converted to a fibre line of which should be at the same subscription amount. On 13 April 2021, I was totally surprised when I received a number of messages advising the contract has been converted to a pre-paid number. I tried getting clarity on this countless time of which none of the consultants were able to assist. Neither did I get a call from a consultant advising me of the process that will be followed. Is this the pathetic service Vodacom offers its customers?
