i took a contract with her last year in November

I had a problem with my phone around April it was rebooting itself then i took it back to the shop for repairs then I asked the consultant that assisted me to check if my insurance was active and he told that my phone was not insured but when i took up a contract i asked for insurance and requested my debit to go off on the 20th of every month, last week my phone fell and it broke the screen and i went back to Ivey i showed he my phone and asked if is there anything that can be done to fix my phone she gave me bad attitude telling that it cant be fixed and i asked about the insurance issue she shouted politely with the attitude and pulling her face telling me that it was my fault that the insurance lapsed because they debited my acc several times on the last day of the month but the was no money
