I ordered Bosch O2 sensor per their catalog, part listed was not correct, contacted by email -could not call to resolve, advised I expected full refund with shipping, was emailed back RMA- returned part, was refunded only cost of part -not shipping or return shipping. I made 2nd email request for shipping re-imbursement since error was not mine. Today I received response. PartGeek takes my satisfaction very seriously and to prove it they offer free shipping on my next order... which will never happen.
I responded the PartsGeek Customer Support Staff, "Strike 3"
