poor service

I took my Huawei phone to MTN Carlton center shop no 204 for repairs on the 28th of November 2017. I was told that the phone will couriered to the repair center within 24 hours. I was told the repair center sometimes takes 2 months before returning the phone which ridiculous on its own. I went to the MTN store to follow up on the 17 of January 2018, they gave the contact number for the repair center. When I called, the repair center told me my phone wasn't sent to them. I then called the shop on the same day and informed Zandi at the store he told me they sent the phone to the warehouse by mistake and he will ensure that the phone is taken from the warehouse to the repair center and give me feedback. I then called the repair center on the 2nd of February, the phone was still not there, i then called called Zandi again who said he will follow up and get back to me. I'm still waiting. I send Zandi an email yesterday (6/02/2018) after contacting the repair center again, the phone is still not there.

This means after more than 2 months without aphone, no work has been done on it yet and its missing. I can no longer wait, this truelly terrible customer service
