Shocking treatment of client of 30 years!

After being a Vodacom customer since 1996 I am disgusted with their service. As I have not yet upgraded my phone to a new contract, I was contacted and told if I don't upgrade, I will be charged more from the end of the month. I agreed to the Honor phone, but I don't want a 3-year contract. I went to a Vodacom store to see if I could get a better package only to be I had to accept the phone being sent to me and then return it. Then we can discuss my contract. I sent Customer Care an email...nothing, no response just a void. The best is after 21 years of a new surname; Vodacom still can't change my surname. Why am i not surprised at this company, once their phone has been returned via courier, I will NOT be renewing a contract with them.
