Terrible service!

My complaint begins with the attitude of your call centre regarding lost data on mtn's side. I have an authorised person on the contract I am on for the past 6 years with no problem getting information and making queries, even upgrading three weeks ago wasn't a problem, now it is and it's my problem to fix it? I don't understand why i now have to go through the entire procedure again because of a mistake on your end. Then i have a problem with your communications with me via sms, this morning i recieved an sms saying you were \satisfied with me". I'm not the one providing the service"
