New contract charged for but not implemented properly

I took out a new 'Family Free Me' contract in August. The deal allows for several family phones to share features like data, free calls etc for a single monthly cost. We asked to have 3 of our family phones put on the contract, my phone was already with Telkom Mobile but the other two had to be ported across from Vodacom. In the process of implementing the contract Telkom Mobile disabled my number for a week before getting my number on the contract. They then bungled the porting of my son's phone (previously with Vodacom) and managed to get it suspended from Vodacom whilst still not putting it on the new Vodacom contract, we are now paying both Vodacom and Telkom for this number but are getting no service from either company and the number does not respond to calls or sms. The third phone (also previously with Vodacom) was also supposed to be ported to Telkom Mobile but we are still waiting for this to happen. I have 4 times been to the Telkom Mobile Pavilion shop and begged and pleaded for assistance and the staff member (who I could mention by name) has basically given up on my case and just tells me she 'hopes' things will come right.... Initially the paperwork was bungled and we were signed up for 2 of these contracts, which we were billed for. I don't know where to turn, the staff member mentioned above suggested I contact her store manager but she doesn't answer her phone and when I leave a message there is no response. I am speechless! I have wasted too much time either on the phone or in the store trying to sort this out and there is no response from them.
