Hero Motocorp — My rear disc pad disc plate & calliper has been replaced

Address:

SHYAMA HERO PISKAMORE RATU ROAD RANCHI

I have given my bike to Shyama hero workshop on 29.10.2021. I have received my bike on 30.10 .2021. Just I week before I have replaced my rear disc pad & disc plate, but after coming back from the service center (Shyama hero workshop) my disc pad has been weared out and I came to notice that my disc pad & calliper is also not the one I have replaced one week earlier.I came to notice this because I have purchased two disc pads so when I opened the disc pad it was a different one from that I have replaced.This is a very shameful act, whoever have done that .If my complain doesn't seem to take seriously I would not be giving my bikes in any service center.I have already lost the trust.
