Poor Service Delivery

I have Sent my phone for repair and I got a quote for close to R8000 for repair, then I requested that my phone to be returned and paid the carrier fees on between 29 & 30 May 2015. I have not received it yet, they have been holding it for about 6 months and I have finished with the contract on July 2015. I have been calling and even going to the store for follow up but nothing is happening. I have been patient but this is to much.<br> <br> Please assist with this matter.<br> Bangani
