Complaint Review: Best Academic Help

This Company named Best Academic Help provides Academic Help for University assignments.

I have contacted them and agreed to take their service regarding my assignments.
As time passed I discovered that this company cheat on clients by providing copied work with no quality and not appropriate to the requested subject.

I made three orders, and they delivered two but with no quality and not related to the subject given.
for the third one, I asked for a refund of the money because I decided to not continue with them.

Regarding the refund, they told me that they need to engage one Legal Advisor to make an investigation into my University if I used their works (in fact I didn't use any of them) and told me that I risk getting out of the University and deported back to my country because this is not allowed.

In fact, I searched before and these companies are legitime in England to offer their service, as I am an international student I struggle with academic skills for this I hired them.

I got afraid and asked them to stop "this process from Legal Advisor" and they asked me for 1950 pounds to stop it (cost decided by the education department). They offer to pay this sum for me as a favour and one of them sent me a false invoice on behalf of the Department of Education.

These guys are very dangerous, they act on behalf of the government and cheat on people to get money.
