Complaint Review: Cyber Infrastructure

I've worked with this company twice now. The first time I paid them half the money upfront and half the money after they completed the project. They worked diligently and communicated with me perfectly. The second project I paid them in full upfront. They quoted be about $400 for four days worth of work. They took an entire month to complete the project. Because it took so long, they said they would complete the project and give me my money back. When it came time to give me my money back they refused. I showed them messages where he said they would refund my money and they still refused to follow through.

I'm very disapointed in this.
