bad after sales service incomplete products

ordered and paid for a food processor on 6 March via shop4tools. The supplier apparently was HOLB, Was then told there was no stock but i was patient. Received item on the 4th of April with 2 parts missing. Emailed shop4tools who referred me to HOLB. I did receive a call with a promise that an email will follow (13 May 2018) After 5 e mails to shop for tools and the warehouse "home of living brands" I have not received any positive feedback, e mails are received and not responded to by HOLB. Emails from HOLB has no contact information of the company. When i called them they did not have a clue who i was looking for? I want them to refund my money and at their cost collect the item.
