Terrible client service

I wrote a review the last time about how this company is horrible and that I've been trying to cancel my tracker since I sold the car in July already. They responded and said they would be in contact with me to try and see how this matter can be resolved. I have not heard anything from them till today. I decided to cancel the debit order with my bank and reversed two installments. Within 24 hours they sent me SMS's on the debit orders that were returned and that I should make contact with them. Clearly all they care about is the clients money and not their requests. I have asked for the recording, and I have been waiting for over 2 months now already. This is a horrible company, I'm so disappointed.
