Pathetic provider (no service at all received)

MTN used to have an online application under "my contract" that showed on the computer as MyStatus, and included ALL you MTN numbers. It worked! So they get someone to develop a new app that does not wor****!!!!!!!!! On down loading the app to my cell phone (MTN number) which leads with " New, just for you",... and continue to login; enter cell phone number and hit continue...Alert No valid content to display! This app is just a poor as trying to get sense from dialling 135. I have three numbers with MTN, on the old system I could see usage for all three. Now I cannot get any information on usage, all they do is cut the connection when data is used up. You have to trouble shoot why connection is down. This service from MTN is so poor as an email to customer care is ignored ad nauseam. No one gets back to you...ever. An example of the absence of service on 135 is when you get through to the point when they ask you to enter a number that you are enquiring about, which in my case is a wifi data number, the online response is log into the website!
