worst experience - not trusted

I have placed an order with online car parts on the 22nd may #TDBYDLL it is already the 4th of June I am now waiting 2 weeks for a car part , they do not respond on emails they do not answer any call center calls it dials dead and they speak to a person like **** on whatsapp 1 response no apology, i was informed i would have my car part by now but yet i am still having to find myself running after them to see if i can get an update after receiving empty promises their call center will put you on hold and end the call . at this point i just want answers or i wil have to chargeback my funds from the bank
