Please call me back

I am trying to take a contract at istore fourways mall and I have been there 3 times and everytime they try to process the application, they get an error saying I have 5 lines active under my account, of which it's not true. I went to the telkom store and they checked on their side and they confirmed I do not have five lines open under my name. I am honestly getting fed up and I have been a loyal customer. My number is ***
