1 MONTH STRUGGLE FOR HELP ON NEW CAR. NO SERVICES

It is 1 mnth since I bought a new car that has to stand in a garage due to fault on alarm system. After the 2nd day I got the car Tata was informed off the problem. After 2weeks the alarm could not be dissarmed due to the battery beeing flat. I phoned the salesman after hours and he confirmed that I as woman have to dissconnect by battery. He promise to have it solved. The person from the alarmsystem made arragements to come and check the car. I took off from work and up to this day he has not even phoned to cancel the appointment. After 2 weeks I contact the Wesbank to see if they could anything out of Tata. It is now another 2week later with no answers. It was on Friday afternoon I received a call whereas as was told that the Salesman Flip is in hospital so does this mean that if someone is in hospital nobody assist in a clients problem. This person assured he will look in to it and come back to me in 5min. The weekend has pass by and no call again. Is this not a problem Wesbank had to solve even though Tata did not respond in any way. I have told Tata and Wesbank after 1mnth struggling to find help this car must be removed from my garage seeing that it is of no use.
