Bad experience ever, Lawyers next

Struggling to get hold of them, no CUSTOMER SERVICE AT ALL! Stuggling to get them out to remove the tracker from sold car to my new car no one came to the party, I asked to be canceled and they mentioned I must pay cancelation fee which doesn't state or wasn't mentioned at the start, I'm paying a fee stil up until today and I dnt have a tracker jn my car. Very disappointed my next step is lawyer.
