After Sales Department ***********

I have done an upgrade on my contract and ordered a new device. The courier company came out to me last Wednesday but I failed the biometrics test. When I called in to the call center they keep telling me to phone DSV when I call DSV they tell me MTN needs to unpause the order. What is going on? Today I called the call center I was put through to 4 different people in 4 different departments and no one was able to assist. Is this the treatment I get for been a client for over 20 years. If this is not sorted by close of business today I'm cancelling my contract and moving to another service provider. Please get staff that are more efficient and know what they are doing or alternatively send them for training.
