terrible service

these guys have terrible service ...its hit or miss in the last 2 weeks i placed 3 orders ..first one was mysteriously discontinued after i ordered so there was no charge..second order was the same way mysteriously one of the parts was discontinued after i ordered ...they didnt charge me... but i paid for 2 day shipping it took 2 days to gather the order some came from dhl still waiting on parts from another currier over a week...they refunded my shipping..but i havent recieved it yet ...when the parts came 2 items were wrong i emailed to complain and they said sorry ...and mysteriously those parts in the color i ordered are discontinued ???? again....i sent them part numbers for new parts to replace them...they want me to pay shipping to return the wrong parts then they will asses and send me the new ones....they stopped replying too my emails when i told them im not payin for their mistake ...they should send me the new parts and when they arrive i will release the wrong stuff with the currier.....
