One of my brothers once had the misfortune to work briefly for this company.
The owner of the business has served a lengthy prison sentence in the past. I can't say too much about him in case this answer gets wiped.
They pay their staff a very very basic salary and the staff have to make their money on commission. The salesmen can be aggressive and the calibre of the staff in general is poor. The office my brother worked from had a woman who answered the phones and when it was quiet she kept nipping off to her other job as, ahem, a lady who is paid for certain services to men!
The work can be of a shoddy standard and the firm has use bullyboy tactics against people who complain.
My brother was in between his previous job and a place at Uni to do a postgrad degree when he took the job. He stuck it for a month.
