I WANT A REFUND! PATHETIC SERIVCE!

About a week ago I called the call center to confirm my contract cell number. I spoke to Primrose who gave me an incorrect number,I noted its incorrect after purchasing data and not receiving it. I then called back and spoke to Ayanda who confirmed as per Primrose's note's on the system she had provided me with a wrong number but didn't bother to call me back. Ayanda promised to escalate the issue and til today I have had no call or feedback from a manager.
