Bajaj Auto — Shocker problem

Address:

16 new Ballygunge road kolkata 700039

My name is sonu kumar das and i owne a bajaj platina h gear 110 and in my warranty period but the problem is i service in osl bajaj topsia and from the past month i have been travelling to the showroom and the only excuse i am getting is that they dont have the back shockers in stock. I am here to complain this because i have only time till october 13 for my warranty to finish...
Im stuck in a position where i don't knw what to do as i work as a zomato delivery partner and i travel approximately 100kms per day as my job asks for such decipline and work from us
I urge you to guide me so i can enjoy riding my bike to the fullest
