Fraudulent Green Connect contracts

I just got a call from a call centre of their lawyers claiming that I have an account with them and they are due to hand it over.

I have no account with them and in fact I didnt know of their assistance until the call centre call came this morning.

This then means fraudulent contracts are being issued to fraudsters without proper checks and balances.

I have asked for them to provide supporting documentation to enable me to refer this matter to my lawyers.
