Vodacom sucks

Good Day

I have done a new contract through Vodacom on my number and its gone through on the grans number which is not my number, anyway I received my phone 29.01.2019 and realised that I was getting all the communication and all of a sudden my gran got the tracking number for the device, only to find out the wrong number was used. I am very angry at this point in time as the phone needs to go back to Vodacom warehouse and then a application will be done for my number, if this was done right in the first place.

now apparently my number wont work on contract, where have I every heard such **** in my life, my number has worked perfectly fine for many years now so why would it be a problem if I migrate it from prepaid to contract?

I am wanting answers on this from customer Care Manager today still and don't ask me to call anyone, I expect a call back and this to be resolved.
