still waiting for a cancellation

Since my last complaint on the 8th of July I have called MTN at least 4 time requesting MTN to please send me a \Qoute"on what it will cost me to cancel my contract. The first 2 times I was told I will have it with in 24 hours. Well that never happened. The 3rd and 4th time I was told ill have it by the close if business. I am still waiting to receive this. You really battle to get through to the call centre and when you finally manage to speak to a consultant nothing happens. I actually have no words to explain how badly the customer service has deteriorated at MTN."""
