SO ANGRY WITH FOSCHNI CELLPHONE INSURANCE

I bought a Blackberry Z3 phone for my daughter at Foschini Online on the 03/07/2015 with cellphone insurance. Almost two month after the purchase date September 2015 the screen went black & gave charging problems with an original charger. I took it to Markham North End PE. It went for repairs & came back in October 2016. Four months later after the first repair, it gave the same problems; on the 08/02/2016 I took it back to Markham. 21/09/2016 took it back again same problems & the screen broke. On the 05/09/2017 same problems BUT this time they said its “mechanical/ software” issue that they do not cover. I have been sending emails to Foschini each time I am taking the phone for repairs to get help of what can be done except repairing something that seemingly gives problems a month after repairs, how many times d I need to return the phone for repairs before they can replace it. Now it’s something they cannot cover whereas they have been doing it 4times before. To me they are aware that it cannot be fixed but they just fooling around to avoid giving me a new phone. Yesterday the 18/09/2017 I called the insurance company at ********** to raise my unsatisfactory, spoke with Keabetswe & I cancelled my insurance because I wasn’t happy.
