Bad client service!

Goldwagen Villieria great service when you purchasing parts ,but if the part is returned because it malfunctioned, then they expect you to wait for their supplier to evaluate if its caused by you, my mechanic handed the flywheel in more then 2 and half weeks ago ,and they do not have the common decency to keep me updated after asking the manager to sort it out ,She just tells me that it takes 14 days for their supplier to view and evaluate the item, while I sit without my vehicle for nearly 3 weeks now.They also forget that the mechanic has to be payed for re-installing the Flywheel.Just very concerning that they are willing to treat clients so badly !...and not take any responsibility !...I will definitely not purchase spares from them again.
