LIVID, FRUSTRATED, ANNOYED - cannot begin to explain

I have been trying to cancel my contract early for a month now - still frustrated and getting no where! 4 April - called them to get a settlement figure for my contract. 21 April a response with a call to let me know the figure but I'm told to wait for the confirmation email which has the bank details on to settle the contract. Needless to say I never got this email, only to be told after going into the branch outside Canal Walk Cape Town today for the second time that this was sent to an old work email address, which I left nearly 3 years ago! Strange how my statements seem to arrive like clockwork every month to the correct email address... I went to the store previously too last week on 28 April after not getting the confirmation email and was told all that they can do is email the Retention's Dept and will copy in the stores Supervisor. I was assured that I would get a response no later than Tuesday 3 May as Monday was a Public Holiday. This morning after no response, was the second time I went into the store and they then called the Retention's Dept and I was told of the email sent to the incorrect address. Stupidly, I have been and paid the account in full and am currently on hold with Customer Services on 808 (this is my 3rd call to them today as the first two times I was told that they cannot transfer me to the Retention's Dept from the 808 Freecall line but I was given a different cell no to call, turns out its a fax line! the second time I called I was given a different cell no, which is no longer in service - hence this is not my third call and I'm still on hold for 47:03 minutes to speak to a Supervisor) ANNOYED AND FRUSTRATED IS AN UNDERSTATEMENT - why do we always settle for such appalling service! You try and do the right thing and this is service you get, I am not at all surprised that people just cancel Debit Orders and don't let them know. THE SERVICE IS SHOCKING, even when I return to SA I will never again be an MTN subscriber!
