Just unacceptable

Well the tracker was installed in my Husband's car by the request of Dial Direct!!!... And they made it clear that it will be at their cost everything but tell how my husband was told to pay a certain amount and now that money is accumulated? With their non-working app and even worse when they requested to add the tracker another tracking devise was there already and they were made aware about this! Now the car is complaining about the bettery. The bettery is constantly running off!!!
