Notary Cloud - I should have paid attention

I did one for them last month. After accepting it I saw the reviews and was fearful but decided to go ahead anyway. There were issues and I had to make 2 trips as the wife wasn’t there the first time I went. I called them to advise them of this and they won’t answer the phone or call me back as I wanted an extra fee for the extra trip and rearranging my schedule. They called back after I threatened them to not go back unless I heard from them. They agreed with my extra fee. The next morning when getting ready to ship the packaged I decided to look on their “Cloud” and they had not changed my agreed fee. So I called again. No answer and no return call. At this point I’m thinking my chances of getting paid are very slim. So I called again and sent an email telling them I had their loan package ready to go but I refuse to drop it unless they pay my full agreed on fee through paypal immediately. It took them about 5 hours to do it but when I sent the last email telling them my final pick up was in 1/2 hour for that day and I needed to know what they were going to do I did get my money sent through paypal. This company steals money from notaries. NEVER work for them.
