Poor online service

I ordered 12 items online and received 11. Ive been sending messages via the contact us form , ive send and resend and i don't get any replies. I called Sandton store because there is no head office contact number on the website , so i requested the contact details they only gave me the landline. I have been calling that line for 3 days everyday and there is no answer. The price of their items doesn't go with their poor service.
