mtn arrogant call center operators

I had one of the worst experiences with the call center, I am not happy to give my id number to anyone once i have had a call transferred, mtn has a solution called the mtn pin so I went through the inconvenience of getting one, I called the call center and used the pin and it worked, UNTIL i got transferred to the retention department, they refused to accept the pin and insisted on my id number in fact the staff were *********** AND RUDE and basically said to me that they would not help me and they don't care what I say about it (they should listen to their calls they will be absolutely shocked how i was treated) retention department, and when you as for someone senior you just get told that they won't put you through (WHO DO THEY THINK PAYS THEIR SALARIES WITHOUT CUSTOMERS YOU DON'T HAVE WORK). MY FOOT I AM CONSIDERING MOVING MY CONTRACT TO VODACOM ONCE IT EXPIRES JUST BECAUSE THE WAY I WAS TREATED TODAY. I wish i could put the call on here for everyone to hear.
