Pathetic service

i called you call centre on Monday to find out what would be the outstanding balance that i need to pay upfront to cancel my contract and get an early cancellation letter. i was told to contact the retentions department on ***, i call the number which was out of service, i call 808 again and was told to call ***, once again out of service, i call 808 yet again only to be told that a request needs to be sent to retentions to call me which will be done in 24 hours and guess what I AM STILL WAITING FOR A CALL...this is disgusting service. should i not make sure that my bill is up to date i am the one that has to pay the price, yet it is ok for mtn to not deliver on their promises. you guys are quick to take money from the consumer. judging from the feedback from the guys on hello peter, i will be lucky to get a response this week still
