BookMyBai — violation of replacement policy

I got a cook from bookmybai in bangalore and i paid the full amount to the company. The cook stopped coming within a week of joining without any notification. I contacted bookmybai for a replacement as per their policy but they have not responded yet. I have been trying to connect with them for the past two weeks but no response. I would like my money fully refunded given the absolute irresponsible & unfair behaviour of the company.
