There is an name mistake on my R C book. i have contacted the show room(SHEGAL AUTORIDERS PVT.LTD) Multiple times but there is no replay from their side i have been waiting for this around 1.6 years. i already submitted the rc along with my documents on 28/08/2019 still there is no replay. when i contacted the show room the behavior of customer support is very poor and they have been harassed me by calling multiple times on the showroom. please give me a replay ASAP possible
yours faithfully
