Porting to Vodacom a nightmare

Abouy a month ago I ported from Telkom Mobile to Vodacom, worst mistake of my life. Porting took more than 3 days after nymerous calls. The phone worked well for about 3 weeks and then it stopped work. I contacted Vodacom and the consultant promised to call back and didn't. When I called again I was adviced to call the porting department. They told me they have escalated the matter to the porting team and I will get a resonse within 24hours to 72hours. I never received any response. for more than a week. It's almost 2 weeks and my line is dead. I can't receive calls or make any calls. I can only send an sms or receive and sms but can't make calls or received calls. CAN YOU PLEASE ALLOW ME TO PORT TO ANOTHER SERVICE PROVIDE SINCE YOU CAN'T SERVICE ME. I HAVE AIRTIME WHICH I CAN'T USE AND HAD TO GET A TEMPORARY SIM CARD TO MAKE CALLS. HAVE TO RETURN CALLS SINCE I CAN'T GET CALLS.
