Not willing to help when needed

we installed a new tracking device about 2 months ago in a vehicle we bought. We need to take this vehicle back to the dealership tomorrow as something went wrong with the deal. I phoned Netstar on Tuesday, just after we learned about the issue with the deal to arrange for the device to be taken out and kept till we get our new vehicle that will replace the one we bouht. I stressed to the call centre guy at it's quite urgent as I do not know where this vehicle will move to once we give it back (he mentioned that it will be very expesive to buy out the contract hence the reason to rather remove the tracker and keep it for the next car). i phoned every day this week to find out when this tracking device will be removed and the only answer i get is that the installation department will get back to me. i need a manager from Altech Netstar to phone me ASAP as I will not take any further responsibility for this tracking device and will not be liable for any other costs associated to this tracking device. I've done everything from my side, but clearly you are not in the business to help your clients.
