Anyone use DragRaceCarParts.CO ??

OK, here's the latest info. I never received a reply to my telephone call on 07/08/19 so I called again on 07/12/19 and was told (by the same person I talked to before) that he still hadn't heard anything from the warehouse. He also said he couldn't imagine there would be a problem since it was obviously their mistake. He promised, again, to contact the warehouse and would call me.
(07/15/19) No call or email yet so I called again. No answer to my call, it went to voicemail and I left a message
(07/16/19) Still no call or email so I called again. And again no answer. Went to voicemail.

I called Holley and spoke to one of their carburetor techs asking what can be done to convert the downleg booster carb I received in error to an annular booster carb that I ordered. After putting me on hold for a very short time, surprisingly the tech told me that Holley is going to do a free courtesy adjustment on my carb. I'll ship it to them, they'll convert it to an annular booster carb and return in to me. Return shipping to Holley is my responsibility, but they'll convert it and return it to me at no charge.
I'm interested to see if they send the same carb back in the Quick Fuel box that's currently marked "Q-750" or if I get a box back marked "Q-750-AN" which would lead me to believe they simply exchanged carbs. We'll see...
