BAD Customer Service and none resolution of issue

I am very annoyed at the moment with the service I am receiving from Vodacom. I took my Huawei P7 phone in for repairs at The Glen Vodacom beginning of November. They took the phone in and did not offer me a loan phone. From the 5th I kept receiving sms' that updated me on the progress. Two weeks after the sms' stopped, I then went back to The Glen to enquire about the phone because it had been 3 weeks. I was told that the phone was not back and there's a high possibility that I might get a new one and to come back on the Monday. In my frustration I continued to use an old phone I had in at home while continuing to be debited an amount of R429 which is my premium amount. I went back to the store again for 3rd time and to my dismay I was told the phone was not back . I refused to leave until the technical manager came to assist. He informed me that the phone was not going to be fixed and I needed to choose a new one, he then went to the back to print out a list of phones I could choose from. Two minutes after he came back without the list to inform me that I can't choose a different phone but another P7 is on the way . A month later I still don't have a phone...I'm really frustrated
