worst service by far from MTN

The worst ever experience I work from both home and Branch as it stands I don't know exactly what is the update with the upgrades I did with MTN when I app**** for this on Friday 28th I was told I will get an SMS by close of business on the day which I did not. With the offices closed over the weekend it meant I had to wait until Monday, Monday morning around 9 I called to find out what is the status on my upgrade I was told that they had been approved and DSV will contact me between Tuesday and Wednesday it it Wednesday today I called the contact centre where 1 agent advised me that my parcel is with DSV they even transferred me to DSV only for DSV to tell me they do not have my parcel on their side. I called again and spoke to someone else who informed me that the phone are packed and ready for collection by DSV at the warehouse. Now I don't know which information to believe now I apparently have to wait for Friday DSV will contact me. This kind of service is absolutely ridiculous considering that they will have to deliver and if I do not have the correct details I am unable to plan my week so that I am available on the day of delivery. how do you have 1 system and your agents see different update on my profile really confuses me. I had the best experience with the branch had I known this is how bad your contact Centre service is I would have finalized my things with the branch
