Mahindra Two Wheelers — Seat lock is not working

Dear Sir/Madam, I bought new Mahindra Gusto in Jun 2015 from Alfa Motors, Domlur, Bengaluru.. From beginning seat lock is not working. When i gave it for 1st service, I informed them very clearly about the issue and after servicing also it is not locking. From Thursday ( 6th Aug 2015) i am following up with them and they are telling that, they will come and resolve this but i am sad to say this, till now no one had come. Being a prestigious company, you should give value add for customer complaints and you need to respond them properly. Highly unsatisfied with your service. Regards, Pallavi
