Round and round and round

I am totally disgusted in the service I have receivedal from Vodacom Repairs and Customer Care. For months my expensive Samsung S7 had been round about the repairs process with no one owning the issue. I have been shunted from pillar to post round and round and round with still no resolution. Some say my phone was blocked by mtn but it wasn't. some say no no its blocked by Vodacom but some say no its not. It works with an MTN sim. Who actually knows. I think I will change to mtn and actually be able to use the phone. Now how do I get the money back from all the months I couldn't use my phone. oh and biggest joke ever you cannot complain to someone. You have to send an EMAIL.
