Family Auto Sales

I put $1500 down on a car from them in January and paid $75wk every week and always on time.Last month we got a job offer to make more money but it meant going a week without a paycheck.I called and asked if it would be a problem if i just paid 2 payments the next week and was told sure that's no problem. 3 days later,I woke up to no car.They got it and told me I'd have to pay a bunch of money to get it back.When I asked why he didn't uphihis word,he denied saying it.I decided I'd rather do business with honest people,and since I was told the air worked in an and by summer when summer hit,realized it didn't,I'm better off going elsewhere.
