bad service

I purchased a car at auto pedigree in southgate from a slaes man called Sanny and it had faults which they had promised to fix, the car had worn out tyres and i went back, they changed them. They had also promised to change the button windows as they were not working. even signed on my contract for that. i took the car back they took it to meadowdale for 2 days and still both buttons were not fixed. they kept on saying they've ordered the correct buttons and never got back to me up until now they call me to come and upgrade my car. when i told the sales guy Sanny that they still did not fix my previous issues but now they want me to upgrade, he just kept quiet and never answered. when they want a sale they tell you who you must say referred you to them so that they can get the referral money, they give you their friends your number to contact you for an insurance. you end up paying for things that you dodnt know of. A tracker company started debiting my account and when i asked the dealer if the car had a tracking devise they said they dont know anything of that sort but those people had my details and were debiting my account. i kept disputing them cos they could not even send me any form of contract or which tracking company they were up until they handed me over. auto pedigree does not keep their promises, and once theyve sold you their problematic car they dont care about you at all. thats what they do when they are done with the sale they do not care about the promises they made and dont sort out their issue. now i must fix all issues related to the car and they just dont care.
