Extremely Dismayed With The Service Received

I sent my Sony phone in for repairs on the 18/12/15 (the charging pin was damaged )and this was the second time i sent it in. The 1st time i was told the phone was not repaired they upgraded the software only. The second time, it took nearly a month for me to receive my phone and actually nothing was done. I called in to inquire but they always made lame excuses i received the handset today and i am so disappointing that nothing has been fixed. I've been a loyal customer with cell and i am so hurt to receive a service like this. I cannot be paying for a phone that now doesn't even make me smile when i look at it. Please can you help me with this problem. I do no want this phone....and cellc needs to apologize for doing this to me. I feel as if i am giving away my money for free. To be quite frank, i cant wait until this contract ends so i stop doing business with them. I would rather move to Vodacom or MTN, who i'm sure would not have done this to me. I called Cellc on the 11/01/16 and they said my phone was still at Sony but i received and email stating my phone was dispatched on the 08/01/16 from Sony to them? why do they lie?how can it pass testing when actually nothing is done
