DT Profab business practices?
I can't offer any explanation for non-response from DT Products - only have my own experience to relate.
I purchased a product from DT Profab for my Dodge Ram, and after receipt (and much deliberation) decided I wasn't sure about whether I really wanted to install. Hoping to avoid loss of a restocking charge, I called and asked David if he would consider an exchange. (Exchange of one product for another, less difference and shipping. ) He agreed to do this, and I returned my initial purchase. After three months, I had yet to receive my replacement parts. I called - several times before getting any answer. David's excuse was that he had been too busy, and had not gotten around to completing my exchange. This seemed unacceptable to me, since it was only costing him an extra half-hour of his time, plus it was like getting profit on two sales in addition to gaining twice the profit on one item.
I asked David when he could refund my money, less his restocking fee. He did complete that transaction fairly quickly.
I won't do business with him again. Also, my experience occurred some time ago - I refrained from posting this for a long time. But, I have seen plenty of negative comment about DT Profab since that time. I don't approve of his business ethics. His mediocre products (at best) aren't worth the trouble.
Hope this helps,
John
