Continental China - non existent customer service

Continental China brags about being in business for many years...... don't know why, their customer service is non existent????

Their website gives NO customer contact details, you have to go via a stockist or contact their factory shops, they also have NO pricing on their products ...????

I have sent 3 emails to the Johannesburg Factory Shop with a detailed spreadsheet of what I need - specifically addressed to DAVID ..... david@cochina.co.za - I have had NO response, not even an acknowledgement of receipt I know the mails have been read, as I put a "read receipt" notification on all my emails

They should replace their slack staff or offer a customer care contact person ????????????????????
