Std Bank Mobile Pathetic service

Pathetic service from Std Bank MOBILE: I was promised I could keep my Vodacom number on the Std Bank MOBILE network, (port my number to the Std Bank network) Debit and Credit card transactions for data rewards. After activating the sim, I got a message stating my new Std Bank MOBILE number. I sent mail to SUPPORT at STD Mobile (twice) no answer or call from anybody. Can somebody please help.
