Terrible service from Mahmed Mohamed

on the 14th of March I wrote a review about the terrible service from cartrack and then got an email from Mahmed Mohamed, he requested a copy of my Bank Statement which I then sent to him again, mind you this is the third time I've sent cartrack my bank statement, I then get a reply from Mahmed asking for a proof of payment to which I asked how do you get proof of payment for a debit order when it clearly shows on the bank statement that I was debited, then to top it all off I get bombarded with calls every single day from cartrack why guys why is your service sooo damn ****py, at this point I'm considering reversing all future debit orders with cartrack for their ****ty service, fix this **** by COB today otherwise all future debit orders will be reversed and ya'll can remove the unit from the vehicle and I will not be paying a cancellation Fee!
