Not supporting nature and maloperating

I've Faire car and using since 4 yrs. Before 20 days my car 3 ,4 and 5 gear was not operating properly so I visited to Local showroom. But there i get wrist responses. My car is in extended warranty period but they deny my warranty and told me repair expense more than 1 lakh. Also they told me first you must service car here and sent me message of amount 16000 / After servicing car we all put your car problem for approval. I service my car regularly in your showroom and then due to my transfer I could not visit showroom but I regularly service my car in private. But they denied my statement. While giving my car in hands of showroom 1,2 and reverse gear was working properly. But when I disagree with them about servicing and told them I won't servicing now because before 5000 km i service my car. They told me if you don't service we are not able to sent your approval to Maruti. Then I told them first consult with Maruti management but they didn't. I realized that showroom is not supporting me. Then I told them I don't want to work here .Give me my car i will do work elsewhere. At that time I come to know that my working car is not start. I asked reason how it's happen but they told nothing. Before that they opened honey and interested with mechanism so that car was not ti start. So I call car and toe my mar and give it in private. I am repenting now on purchase your car and extended warranty. Your service is very very cheap.
