Disgusting service from i store Clearwater!!!

I did a trade in at i store Clearwater on Friday and I selected the cash back option. I was told they would do an eft but up to today I haven’t received the money. I sent an email and called to follow up only to be told they are waiting for the finance dpt to process the payment. They already took my phone and now it’s difficult for them to pay me. We are tired of these big companies taking advantage of consumers. They wouldn’t let you walk out of that door without paying for a simple charger !!! Wow
