Goodbye Vodacom hello Telkom

I have been a customer of Vodacom for about 18 years. I have 3 devices on my contract and pay R1050 a month. 2 years ago I upgraded my contract and it came with a promotional phone for my son. Now last month I upgraded my sons phone. The phone arrived in store a month ago and they won't release it besause they say that it was a promotional number and the new phone had to be refinanced if I didn't pay cash. My monthly amount payable would have been less than I am currently paying. i have been tryng for the month to sort it out with the store and with the the call centre. The store staff have tried to help but they are being blocked by some idiots at wherever office. I am going to take my business away. The service from the call centre has been terrible with staff that have no idea of how to treat their customers. goodbye Vodacom
