Mtn you guys are useless!!!!

Last week I opened a contract with Vodacom and requested that I keep my current number (which is registered on the Mtn network). I was told that I should receive a message from Mtn with a password which I should provide Vodacom to transfer the number, this I was told takes a maximum of 24 hours to do. It's almost a week later and I still have not received a message with a pin to transfer my cell phone number. I have a friend who moved from another service provider and everything was sorted by the next day, I further know someone who moved to Mtn from another network and this was sorted out the same day. So why are you making it so impossible for me to leave your network?? I considered just staying with Mtn because of the mission it is to move away but then thought why should I stay because of your bad service? The reason I cancelled my previous contract was due to bad service. I've called the contact centre requesting assistance but they didn't help much. I went into two Mtn stores which I waited so long without assistance that I eventually gave up. Why have five computers and only two people working?? Please just send me the sms so I can move away fro m your useless network.
