I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.

The experience is great because there have been some documents that I needed to change, but for the free trial I wasn't expected to get charged at all. It's free for a reason. That's all apart from that, it's a great tool to have.
