VODACOM STARTING TO REALLY DISAPPOINT ME!!!

Last week i discovered that my number was not sending out Sms's even thou i could still receive them, so i went to Vodacom at Cresta on 10/03/2016 to find out what the problem was. One person assisted me and gave me a Ref number to do a follow up on. The Ref Number is AZ-1LKZ-SHX1JG . I was told that my number would be able to send out sms's within the next 48 hrs. The 48 hrs passed and after i called vodacom only to hear that it will be probably done Tuesday afternoon by Tuesday 15/03/2016 afternoon i still encountered the same problem. so i call vodacom on *** and the consultant tells me that that my APN was not activated and that it will be activated within the next 24 hrs and i then will be able to send out sms's. 24hrs passed and still was not able to send out any sms's. So today 17/03/2016 i call vodacom again on *** and the consultant tells me that she needs to make a call and will call me back. I waited for that call and she never got back to me. THIS IS VERY UNACCEPTABLE. I AM NOT HAPPY WITH THE QUALITY OF SERVICE THAT I AM GETTING. NOW I CANT ACTIVATE MY CELLPHONE BANKING DUE TO THE REASON I CANT SEND OUT MESSAGES. I HAVE HAD ENOUGH OF THIS...
