Does anyone know the company “Autoteile Feist” (exhaust price) in 55618 Simmertal? Can you trust them? I ordered a pipe for a super price by cash on delivery. Prompt delivery, but amount by more than 100 € more expensive than the order confirmation!!! My wife of course paid at UPS because she did not know how expensive I had ordered. On Friday I did not reach anyone by phone. On Monday, because bridge day, telephone and by e-mail little reached. Are these serious??? X AX
