Insufficient Info to Contract

The business manager did not explain the rates allocation in terms of how i will pay. I requested to pay less amount to the one presented for a vehicle and she put me on variable interest rate but failed to give me full details of the implications of that plan as a customer until I discovered that for myself. The contract from the finance company was vague about the rate and she did not explain that to me as a customer. I am tired of people who are in a hurry to close a sale or please a customer that they will pay less without giving them a real overview of the implications. To make the matters worse when i contacted her about it she said she \told me\" and she didn't so she ended up not replying back which is a bad attitude to me and she couldn't even apologize or show any empathy to my situation. So can you train Natasha to explain important matters to clients and not rush to close a sale because at the end of the day I'm the one who must pay."
