I am very frustrated and harassed by amazon uk

I am a very small business person from India with limited means. I established my store few months back hoping to sell on it in future however recently when I had a look at my store there was negative balance for which I raised the request on amazon to clarify and no one replied and a week later they deducted 753.10 pounds from my card as “other charges” when I opened the third case they told me it was vat registration charges. I never asked for it and even their is no further clarification on it. when i asked for refund they refused honor my request. I have been begging to amazon to have my money back every day. That money was my 12 month saving to pay loan this Monday. I have been crying to amazon to refund my money back but no one calls or reply. They charged me for the services they never offered and harassing me. I have not even listed any product.

1st of may I raised the request to clarify the negative balance and without any clarification they deducted the amount on 7th may and even after that It took them 5 days to let me know the reason of charges. Upon asking refund they have refused to do so

The chat and E- mail support is incompetent as they keep talking with set template rather than talking as humans. Since than 1st may I had 5 open cases. Is their any phone number or email that i can reach out who can help me as it has been 14 days since I first raised the issue about negative balance.

I will not be able to survive without that money. If some one can help please connect me to right person

Thnks
