BAA and Sales Team Disappointment

Hello!  I was promised a BAA sent over as soon as I paid for the phone service. I paid for the phone service and my sales rep ghosted me - no emails or anything from the MOMENT I purchased the plan.  I have sent him 7 emails over the last week.  I am disappointed and frustrated - I would never have selected this service if I had known he would disappear as soon as I paid. Can someone please help me? He said that I didn't have to make any additional purchases, and that he would send me a BAA over right away as soon as I put my credit card in.
