getting no help on change of ownership

I bought a walka from a lady and she has since refused to do change of ownership. Decided to take the matter to multichoice, as from the 10/06/15 up to date i have been given 5 case numbers. Sent a fax was not in the system sent an email to [Email Removed] rep**** by Tshidiso Motheputo case no(***) to go an agency since i was using a passport. Went to Greenstone got no help. Sent email again got a new case no then sent another 1 to multichoiceenquies got another case no. Decided to go to Randburg 07/07/15 advised to do an affidavit & supporting documents and send them to [Email Removed] as the lady who sold the walka to me is multichoice employee which i dd & got case no *** on the 13/07 called 18/07 ***) spoke to a lady who seemed to be helpful (Munene)sp who said she has spoken to their supervisor and they will load the walka in my account. Even today its not done. The same number is unanswered. Have taken to dstvcare twitter acc, call centre still no way forward. I wonder what kind of service is this sitting at home with a walka with an error message that i can not clear. Shocking
