Hero Motocorp — Having problems in front shocker and much more just after my first bike service

Address:

New delhi

So just a couple of days ago..i went to one of your service center to get my fifth servicing done(singla agencies hero motor cop)i have been facing problem in my front shocker since i got my first servicing done it makes so much sound and my bike's handle vibrates and kind of bounces so much whenever i drive even on the plane road.this problem pop ups again and again whenever i drive.i have been complaining about this since my first service but your service center staffs aren't able to find the exact cause of this problem and to note that it has been worse since my fifth servicing.i have went to them for three consecutive days in a row for the same problem but still they couldn't find the exact cause rather they changed my back break's shoe and now even it makes some annoying sounds whenever i apply break.so its a request to take my problem into further consideration and make it right.. I'd be obliged for your efforts
