POOR SERVICE FROM CARTRACK

I am extremely unhappy with the way I have been treated by Cartrack since the middle of August. So unhappy with the HORRIFIC!!!!!!!!!! terrible service that I have received that I would like to enquire how I can cancel my contract with Cartrack. Since I signed up for the cameras to be installed in both my vehicles...it has been a nightmare. Dates of installation is where it started. I was messed around for 2 weeks. Then a debit order was processed almost halfway into a new month causing my bank account to be overdrawn. I am not getting any technical support at all. Vidoe footage takes day sto download I have made contact several times. All I get is an acknowledgement automated mail and that someone will get back to me but no one ever does regarding technical assistance or support. All get is employees apologies and empty promises from Cartrack. Then again this morning a debit order has been processed on my bank account on the 2nd of the month this despite the fact that I have indicated debit order must run on 25th of the month. Please tell me how this is acceptable. In light of this rotten to the core service....I would like to actually end/terminate my contact as soon as possible. I referred a close friend to you 2 weeks ago. He still has not been contacted. In light of all of the above I think it's time to end this fruitless business relationship and find a better service provider as I now have zero faith in Cartrack and the empty promises. i give up. i am done. i REGRET SIGNING UP WITH CARTRACK. I WILL NOT REFEER ANY FRIEND OF FAMILY MEMBER JUST SO THAT THEY CAN RECEIVE SUCH ROTTEN SERVICE!!!!!!!!!!!!
