Worse insurance company

I purchased a cell phone in 2016 from Edgar Galleria Mall and took an insurance out for the phone, after a year and a half,I changed my bank account, and came into Edgar's Galleria and gave them my new account details, I didn't get debited,so I queried the issue, I was told I was never on the system, so for a year and a half who was I paying?cause I got proof of my Edgar's slip and on my bank statement,I was being debited. Now my phone has never been insured. I do not advise anyone to insure with Hollard, their customer service is very poor and a useless company
