Easy to take your money, horrible to refund

Device was returned middle June 2022 in mint condition. 29th of June 2022 Rentoza deducts subscription from my account. I have since then sent them 10 emails. They rep**** to one saying the money will be refunded. Then a few days later they inform me no money was deducted from me for this specific subscription, that its not showing on their gateway. After sending my full bank statement, where deduction can be seen and showing them how it shows on my account on Rentoza that it was fulfilled and deducted from me, I still have not heard back from them.

About two months prior to this, they tried deducting money from my account, when they phoned me I said within 1 day there will be funds in my account for them to deduct, never the less, they blocked all my devices not even 24 hours after deduction failed. They cant give a customer even 24 hours to pay, but they can deduct money and after 19 days still not refund you
