Is Bureau loans legit?

my husband received an offer of 100k from Bureau loans as we have enquired with various institutions since we wanted to consolidate our debts. They have sent him an approval letter. But we have picked up few red flags such as paying upfront payment towards legal fees an amount of R1800, the interests were unbelievable that it it will be only 4k and the loan is payable in 36months also they don't have land line number as well as their fax is those 086 numbers. Should we be worried. We feel so uneasy to take the offer as much as we want to pay off our debts
