Opel Zone is useless!!!!!!!

Order Complete Cylinder Head at them, pay it then get a call and said the invoice never included tax, after an argument send an incomplete poorly wrapped parcel yeah WRAPPED not BOXED with half of the parts missing and it's damaged. Call them for the parts that's missing, then you have to pay for the missing parts too but ordered a COMPLETE CYLINDER HEAD. 1000 Excuses to refund the money. ****py place I will not recommend them to anyone as it's ****py service and even worst parts
