Tracker Financial Services Incompetence

I sold my vehicle in April 2022 and had to cancel my tracker ( obviously ) . I notified tracker via e mail on 20th April yet the debit order continued . After a number of attempts to resolve i spoke to them on 17th June , resent three e mails and was informed i would receive a credit for their error . I followed up again this week and was advised on e mail today that my account was only cancelled mid June therefore no credit . Incompetence at its best . The sad thing is that i never had a single issue with the primary reason i had a tracker for almost 4 years and now as you can imagine due too this when selecting a system for a different vehicle i have chosen a competitor . The hoops we as consumers have to go through to receive what is rightfully ours . The value is minimal it is the principle , the time and frustration that ends up in a review such as this .
