Rentoza poor customer management

I’ve signed a contract after going through the verification process. Two days later, I was told I didn’t meet the minimum requirement and my order was cancelled. It’s been more than a week and no email response received after enquiring on the reason since the only clause in the contract regarding cancellation is a breach. How can I have a breach, if I never received the device?.I’m not upset about the cancellation. What’s upsetting is being treated this way. I feel completely violated as a consumer after renting multiple appliances and having paid them all with no arrears.
