NO RESPONSE FROM INSURANCE DEPARTMENT

I bought an IPhone 6S from MTN in October , as there insurance rule states that you need to insure the handset 3 months from its purchase date. Since then I have tried on numerous of occasion to insure my phone . <br> <br> I don't have the time to go to the mall and do this everything I do is done online . So I called the insurance department and no one has gotten back to me no one answers , I hold for hours on end. Then I went online to fill out the application for 3 time , still no response<br> <br> Why do you make a facility available and then don't see it through !? I very frustrated with MTN at the moment after being their client for over 3 Years I find this extremely appalling <br>
