Vodacom is pathetic

I have upgraded my data bundles package to a new package and they allocated the new package which is a home internet to my sim card that i'm using for calls,mind you if the package is loaded to the sim card it will only works on the router now i can't get calls my sim is not working on my phone.I called them and they said for the package to be reversed to old one i need to bring back the UPS that came with the new package and i've been waiting for the courier to come collect it.It is my 3rd day now i'm frustrated as that is my main number.
