? on dynamic torque coverters

I ve bought at least 10 convertors from them over the last 10 yrs. I have refered at least 3 customers to them. They screwed me over just 2 months ago over a rebuild they did. I called an talked with Shawn whom ive always delt with. I asked him to take care of this e wouldnt do it. I told him that I would never come back an never refer another customer he could have cared less. Just ask him what will happen if they build a convertor wrong! Ask him about me. Dont get one from them go somewhere else.
