Bad Service

I have had a Vodacom contract for +- 15 years. I received a new contract in April and went to Vodacom Lakeside Mall to do a sim swap as I did not want a new number. I cancelled my previous contract and was told all was well as I could use my old number. At end May the phone could only receive calls and I could not make any calls. I went back to Vodacom Lakeside Mall to query this and was told I could not use my old number and had no option but to use the new number (I told them I could not as I had destroyed the sim card), as I would not be using this number and didn't want it to get into the wrong hands. My old number was changed to prepaid without me even asking for it. The cherry on the top was being charged R1357.50 for data on my final billing at end May. In all the years I have had a contract with Vodacom I have never used data.<br> I have tried sorting this out by constant phone calls and keep getting passed from pillar to post.<br> I must also say that I had disgusting service at Vodacom Lakeside Mall..
