Most terrible service to customer - time & again

I have been with MTN Corporate for some time and never had one positive experience with them. Every upgrade was a nightmare and an absolute frustration!!! 4 times in a row now!!! And promises are made left right and centre, and nothing comes to light. They get an address that is suppose to be Centurion wrong and send the phone to Heidelberg. It is a week later and still do not have the phone. Now new promises of 36 to 48 hours. Unacceptable!!! I received a SMS about the other to be delivered on 10th of March, guess what still waiting!!! I do not even know when the other 2 phones are to be delivered. I have made arrangements to be at the delivery address, but cannot go any further and being inconvenienced by an *********** company or courier company.<br> I am at the office from now on and they can phone to get the phones delivered or make arrangements to do this after hours!! I have been at home for a week to accommodate them, which is over now, they will accommodate me now, I AM THE CUSTOMER!!! And try and leave messages for Chadelle, the calls are just never returned. It is absolutely disgusting service, and after 9 years, exactly the same. You miss the meaning of customer service!!!
