STANDARD BANK MOBILE - PATHETIC SERVICE!!!!

I am becoming extremely frustrated with Standard bank Mobile. I have been trying to port my number for a number of days. I have put in 2 requests via the pathetically useless website and have tried on numerous occasions to speak to somebody at the call centre, but I just go round in a loop of "all our agents are busy". Then when you try leave a message it advises that the mail box if full and you get cut off. How many other dissatisfied customers do you have whose calls you have not answered or messages you have not attended to? Hundreds I assume! I came over to Std Bank Mobile to avoid frustrations and it has been nothing but an absolute irritation, from the SIM card taking well over a week to receive, not 48 - 72 hours. Now my number is not ported after well over a week! I don't know where else to turn for support. The website doesn't even allow you to send a message, not that I think that will receive any attention anyway. I am seriously at my wits end and do not know what to do - HELP!!!!!
