Useless Customer Service

We have been contract subscribers of MTN for more than 15 years, spending a minimum of R6000 per month. You decided to disconnect our service on Monday 6th June at 8:00. When I called to sort the issue out your "Legacy"system, the same system was offline for more than 36 hours so no one could assist me. I mustve made around 50 calls on Monday and after 20:00 on Monday I gave up. On Tuesday after another probable 20 calls of being passed from one call centre agent to the next, cut off multiple times and speaking to a Manager at around 14:30 our lines was reconnected...... Just to be disconnected again on Tuesday morning 9:10... Another call back to MTN and after being cutt off 6 times through the call centre, eventually spoke to a call centre agent just to be told that the pin we have been using for the best part of 5 years, if not longer now does not work anymore and have to go to a MTN branch for assistance!!! This is brilliant customer service I have to say :(((((((((
