I worked for these in 2014. Was there a week, did not pay me for it either. They offer a dreadful service and the people who run it leave a lot to be desired.
Cold calling, and saying loads of satisfied customers.
No proof even when I asked. The sales punchline at interview stage is "Look how the Yellow Pages has shrunk" and how everything is now online, and how they can take advantage of it lol!
Avoid these cowboys at all costs!
