Please return my money and cancel my contract as it has ended already.

Onair is a **** who takes other people’s hard earned money… my contract with them ended in July 2025 but even before then they deducted an amount that I didn’t know what was it for on top they deducted my monthly payment. Now my contract ended they still deducted money from my account. I have been wasting money that I don’t have calling them requesting them to cancel because my contract has ended and for them to bring my money back. They didn’t do that instead they are sending me from pillar to post all of them it’s not their responsibility to do refunds.
