Unproffessional and pathetic service

I have taken up a cellphone upgrade offer from MTN on the 8th of August. Whereby I was told that it will take approximately 9 days for me to receive my device. which I never received. I have been making constant follow-ups and was told my phone was handed over to the courier company called DSV I should speak to them directly.

I called DSV and they had no record of receiving my parcel and referred me back to MTN, which then discovered that they never handed it over to DSV due to their system which was not operational when I did my upgrade.

One of the MTN customer service managers assured me that it will be escalated and resolved ASAP. That was two months ago!! Due to unsatisfying service that I received from MTN I then decided to cancel the upgrade, as I will be billed for something that I did not receive. Even today the cancellation hasn't been done. I have been going backwards and forth with this, been from one MTN department to another, but no one has ever thought that I am a customer and I deserve to be treated like one. I have sent numerous emails, no one bothered to get back to me.

My current phone is giving me problems and I cannot take up any upgrade at the moment until this one is cancelled.

I want nothing to do with MTN, I just want them to cancel their pathetic contract.
