Advice for a newly terminated employee...?

I started a job approx. a month ago. The job was to contact current and potential customers for sales. The first two days, the general manager told me to look around the computer and find what I would need (this was on Thurs and Fri). On that Friday, she told me she wanted me to start making calls on Monday. I have plenty customer service and sales experience, however, I do not know how this company works or anything about their products. On Monday, I arrive on time ready to work. The general manager never showed up...no call...no email...nothing. This was the first of many days that I didn't hear from her at all. After a week or so (on a Friday), I emailed her and told her I felt like I needed some training on policies, procedures, and products. The next Monday, she called and said that she would be there on Tuesday. She did come in on Tuesday, but I only got about 45 minutes to an hour of her time. Then, she was right back to not being there. So really, I received NO training...only answers to some questions that I had jotted down when she wasn't there. To make matters worse, if I did try to call her, she didn't answer. Any emails would take a minimum of 1-2 hours for her to answer. I know sometimes people are busy, but shouldn't a general manager be accessible to employees??? This past Friday, I was working, and heard her come into the office talking on her cell phone. She did this for about 30 minutes or so, before she came in my office and told me that I was terminated. The form that she gave me said that my sales were not what they were used to. I was never given any quotas or expectations for sales numbers. I have NEVER been fired from a job until now. So....am I solely responsible for my termination, or does some of the blame lie with the employer??? I have no idea what to do...it was totally unexpected and my bills are going to fall behind quickly. Any advice would be greatly appreciated.
