POOR SERVICE FROM CAR TRACK

Car tack is absolutely useless they only good in selling products but after sales service sucks. I have 6 vehicles on my fleet but i have endless issues with accurate tracking lately the camera systems stops working in 3 of my delivery vehicles due to so called depleted data, for one I was never informed about about limited data usage yesterday I bought 500 SMS but 24 hours later I'm still unable to view my vehicles and the tracking accuracy is pathetic, Problem is I have 3 year contract since it was installed December/January I brought this under my attorneys attention to cancel the contract and have the units removed This is not my first complaint they wanted to charge me for maintenance call outs which I reported 3 to 4 months ago the told me I'm out of the warranty time frame which I disputed due to their poor service and delayed response .I want the owner of car track to contact me personally as the stuff is full of apologies but ***********, I told them that I'm going to cancel the debit order.
