I ordered a MLB shifter knob on the www.carid.com website. The site will not let you add the knob to the cart without selecting an adapter insert. I selected a M8 x 1.25. I received the knob and a 5/16-18 adapter insert. I tried several times chatting with Melissa and Roy to get them to let me exchange the adapter with NO LUCK. I finally called Customer Service and spoke with Liezel who after two days understood their error and issued me a $15.00 gift certificate to cover ordering the correct adapter. She then transferred my call to Thomas in SALES. He said the adapter was $32.25 minus the $15.00 gift certificate, leaving a balance of $16.25 I would have to pay. Of course I refused. He then went on a sell rampage and said I could go ahead and pay the difference and then speak with Liezel about a refund..... I knew at this point I was dealing with crooks and ended the call. Funny enough, I then received a Satisfaction Survey on a Ignacio Sancho - the SALES guy identified himself as Thomas ????
