Hero Motocorp — I am complaining about my hero maestro edge 125cc

My scooty maestro edge 125cc is facing a problem in battery charging system, battery is not charging when i drive and its consuming battery every time when i use self start and i told my problem to the service center of hero motocorp, they took my scooty for 1 day and after one day i arrive to pickup my scooty and i want to check my scooty, they said we resolve the issue and you take your scooty with you when i force the service employee to check my scooty, when i check in front of him the problem was not solved and then he said it takes 1 more day you will leave your scooty. Is this how a paid minor service works? Fool your customer again and again very worst experience i feel why i buy a vehicle from hero motocorp.
