Well, Al Qaswa Auto Parts were requested to submit the proof of their purchase of that part and they submitted that in the plain white paper without any name of shop/dealer/agent of Mitsubishi. I assume some action must have taken here from SEDD. After that Sharjah Economic Department officer requested me to call the shop again for seeking the immediate resolution.
I was fine for seeking a replacement either as I still need it, but Mr. Boban told me over the phone that they can't order again so they will refund my money. When I visited them for returning, they literally forced me to sign on paper saying - Reason of return: "customer no need" instead of "not working". Salesman: Rajesh was very aggressive, rude and disrespectful in throwing paper around when I wrote: "not working". Wasted my time in argument and when they saw that I won't sign that crap, and was ready to leave the shop they accepted me to sign on the genuine cause.
I really don't know what action SEDD has taken or planning, as I just reported my side of incidents to them and they closed my case after that with an email and SMS confirmation.
