WORST SERVICE AND MISCOMMUNICATION

I cancelled my contract with Jabba Connect on the 8th of June, well within the grace period. They collected the device on the 20th of July and the debit order is still going off. Their consultants call me three times a day and no one seems to be able to sort the problem out. There is no communication within the company and each consultant response is to report it to a supervisor. I'm still waiting to speak to a supervisor. I would love to have my money back but according to a consultant that is not going to happen. I would just like to sort this out as quickly as possible.
