Appalling service and no way to get assistance at mycell.co.za

I am actually appalled by the service I have received. I got a call saying I have been approved as I have app**** online. They then proceeded to take down ALL my details, including my banking details. This went through a verification process and then I was asked to verify again so I set a time, but no one called back?!?! Calling in on the 0873303391 'customer service' number gets you to a consultant which I called about 5 times! They cannot apparently put you through to sales as it is an outbound call center and they have no way of sending them a messages.... They just asked me to hang tight and someone will call me, which still has not happened! I eventually spoke to a supervisor who promised me he would mail the sales manager and you guessed it.... no calls once again! I still want to go ahead with the contract but I'm concerned that they have all my details and will deduct my account without even getting the phone? Don't know who to call anymore......?!?!
