VERY DISAPPOINTED in how they sell their products and after service care

we installed a tracker device 5 months ago and already the price increased. No where in any correspondence were we told by the sales person that it will increase "in fine print" That would have influenced our decision not to take their product and rather the competitors ( with whom our other vehicle is) The lady at the service dept call center was also VERY unhelpful and unfriendly. VERY DISAPPOINTED with this new company we must have a relationship with?
