Disgusting service from PPS

I have cancelled my PPS insurance on the 12th of November 2019 with all needed documentation. They phoned me to ask if I am sure and the agent said it will be cancelled on their side. To date debit orders are still coming off - I tried to phone them but answering the phone is non-existent. I have send numerous emails requesting me share profit to be paid out as well- As per there policy 22 days. To date no money has been paid back. Email states my query has been escalated but no phone call. Service is terrible and they are not getting back to me!!
