Beware of this consulting company. I am autonomous and my manager told me to sign a contract with them (surely charging a commission) to comply with the data protection law. Their commercials are very heavy until aggressive by telephone - they try to sell you their 'online courses', they have made me sign contracts after I had already told them that I wanted to cancel and they threatened me with litigation when I tried to cancel. Your English course is full of grammar mistakes too. I think it's a scam and reading other opinions in forums, I see that I am not the only one who thinks so. In short I changed manager and I keep trying to unsubscribe ..
