Standard Bank Mobile #1 Worst Service Ever

Good day, About 3-6 months ago, Standard Bank Mobile offered me a sim card that is linked to my current account with them. First of all, to get the simcard delivered was a mission and a half (problem 1) and then to get it activated (problem 2) never the less, the problems continues. Each month they were supposed to debit a monthly fee from me which never happened (problem 3) phoned them one time even to supply them with the correct banking details, still didn't debit. A few days ago, the sim's (2)stopped working after i changed everything to this number. I am so furious, as no one can't get hold of me. To make it even more worse, their call centre is only working business hours appearantly, and not like Vodacom, MTN, and CellC 24 hours. Please rectify this and or arrange this number to be ported out. I am done with your arrogance service consultants. Phone me tomorrow to resolve this.
