Very bad service

I joined Z-Fin because I wanted them to remove me from debt review. They asked me to send an email to the company I'm on debt review with to ask for transfer, I did exactly that. Unfortunately that company rejected my request, I came back to Z-Fin to ask them to cancel my contract with them since the other company rejected my request. Z-fin told me it's not a problem they will do that, unfortunately two weeks later I'm still calling them with the same thing and every time I call they tell me about escalation and the lady is rude too. They don't wanna cancel because they wanna keep debiting my money every month. I'm really not happy with their service
