Here is a company touting generosity and goodness, SpartaGroup.eu.
Are they the same company as spartagroup.uk?
They have a single mobile phone number that could redirect anywhere but there may be a clue that they are a single Polish person called biuro if email@example.com is anything to go by.
They have no UK address or company number or company name as is often the case with these recovery companies. Their Polish address is at 28. října 770/6, Moravská Ostrava, 702 00 Ostrava,
They also state an identification number of 07694903
It doesn't mean that they are definitely a scam, but it is odd that they claim they are regulated by the FCA when they are not a UK trader.
This company us pretending to be a UK entity so beware.
