New Client Completely Ignored

Hi Guys. I have purchased an annual accounting package for my new business. The only part that worked well was to get to the payment portion. I have since not heard from you and it is 10 days later. I have written two follow up emails that has gone unanswered. I have tried calling you multiple times and just end up waiting in queue until I give up. I truly regret purchasing the product and since I have had not use of it at all, I wish to be refunded
