If I signed a confidentiality agreement that has my first name spelled incorrectly, does that make it invalid?

I purchased furniture from Rent A Center and it came with bed bugs. Since I had never had bed bugs before, it took about two days before I was certain the furniture came with the bugs, and I found out they were coming from the headboard. RAC sent Terminx out almost two weeks later. Before Terminix came, they had me sign an agreement, which they told me it meant I was agreeing to have Terminx come out. After they came and sprayed my home, I thought the situation was over. Unfortunately the bed bugs came back which means they never killed them in the first place. I went to RAC Facebook page to warn their customers that RAC will infest your home and do little to nothing about the situation. RAC then tells me that I signed a confidentiality agreement saying that I could not talk about it. However the agreement they sent me has my first name spelled incorrectly, would that make the agreement invalid?
