Dissatisfied customer

So today I called MTN to cancel my contract and get a settlement letter for the outstanding amount owned on my contract. I was on the call for a total of about 3 hours. Dropped calls twice forcing me to phone back. I was transferred between 4 different departments and 6 different people. Still nobody could help me. It’s always another department that must help. It’s like nobody has any idea of how to do there job and just pass it to the next person. Still waiting for the line mangers e- mail that I was promised he would send. Still waiting for the letter. Useless service from a company that has no problem taking your money. Give your people proper training.
