Cookware Lamontage

I ordered cookware from Mastercook 2 years ago. I paid them in full but I did not receive my goods as yet. Mastercook was taken over by another company called Lamontage. They do not answer my calls neither to they reply to my emails. The landline number goes to an automated voice service which states that the company will re-open on 2nd October 2017 which has gone pass already. I do have contact numbers for Lamontage which is ********** 946 Phume Lamontage, ********** 406 Sne Lamontage and ********** 058 Silver Lamontage but to date I do not get hold of them. Kindly advise me what to do.
