My phone has gone for repairs for more that 6 mths

<br> I booked my phone for repairs on the 09 February 2015 and I was attended by Lungi Zulu at MTN Mutual mall in Durban. I was told that I must expect an sms from the repair centre that will be updating me about the status of the repair. I waited for two months but there was no sms, I went to the branch and they told me that the phone is still with the repair centre. I sent an email to HVRC repairs on the 10 July 2015 and they informed me that they haven't received my phone from the branch. I phoned the branch on the 29 July 2015 and I spoke to Ndumiso who told me that Ms Zulu was off,he said I must call her the following day or I must drive to the branch. I drove for 7km to the branch, I was attended by Ndumiso who told me that the phone is still with them it is waiting for Ms Zulu to attend it. he told me that i can take it if i want to.<br> <br> I am very disappointed with the service for MTN, how can they keep my phone for six months without booking it for repairs? I just need justice to be served in this matter because I am the customer and I do not understand why MTN is taking away my phone for such a long period. I am now using the company phone for private and business use .<br>
