Hero Motocorp — battery not charging - incompetent service rendered

Address:

Bangalore, Karnataka, 560061

Dear sir, i got my hero pleasure serviced at sai motors - mysore road in march 2019. As suggested, i got my battery changed for the auto start problem.
However, inspite of visiting and re-visiting for the battery not charging, the same has not been done till date.
I have again given the vehicle yesterday, they have promised to do the rectification by today evening.
I am highly dissatisfied with the service rendered (Vishnu, the manager & bharath the serviceman).
