Demandforce review: they increased prices and nobody informed me about it

I signed the contract with the company www.demandforce.com. After several weeks I understood that I made horrible mistake. I contacted the agent and asked that I wanted to cancel the agreement. They told me that it would be possible to do in the end of the month. After that they increased the prices and started to charge me for completely different prices, as well as no one informed me about it. Total scam, so don’t buy or deal with them and post comments about your experience with this company.
