Told to pay 30 pound in email then 130 on phone then once that's paid get told another 150 because ots a business but the loan bank account isn't a loan account its a personal account and when you call them you get told pay 100 pound or you don't get loan even if you have paid what they were asking for previously so in total they want 280 not just 30 pound bank and police are involved due to it being a scam 02071938122
