Scottie's Auto Sales Sold me a car, lied about problems with it and the problems they did say they would fix never did! pawtucket, Rhode Island

I Recently purchased a car from Scotties auto sales, Something I knew I should have NEVER done but do t my financial situation, was an option i took a chance on. When i purchased the vehicle I was told there was no major problems and the ones there were would be taken cared of soon as parts were ordered and received. I was given a 90 day warranty and told that ONLY they could work on my car. i found that strange but I admit my urgent need for transportation to work and to bring my children back and forth to work blinded my better judgement. Well during the 3 month period my car had an issue that forced me to leave it at their shop for about 1 month, in which time they did not take care of all the things they said they would, and kept telling me they'd take care of things.  I took the car to a commercially well known auto service shop who did a complete check of it and printed out a sheet of the problems totaling over $1200 and stated that i COULD NOT have done this damage to the car in the period i've had it.. Well now that the 3 month period has lapsed they completely ignore the fact that the problems hey DID tell me about exist and were to be taken cared of but never seem to forget to remind me that a payment is due. All in all Scotties is a rip off. i advise anyone considering buying from then NOT TO DO IT!!!!!!!!!!!!
