Bolt Discounts and Rude Drivers

What is the point of giving a discount if the drivers do not honor it? I am pregnant and because of my discount, every driver called me and told me "their" price and if I did not want to accept it, then I must CANCEL. Is this now an I-Driver service where I must negotiate? How am I supposed to get around safely if I cannot even get a trip? Does a promo meaning nothing and if it doesn't then why run it? I've used Bolt from 2017/2018 and had no issues before with my discounts... Don't offer and I wont take it, will go back to Uber... and the way I was spoken to means that the drivers don't need our service. Who is paying who? Am I the Customer? Absolutely disgusted by the behavior? And I have met some Awesome drivers over my years but this is enough to put me off for good. And there is no point of Complaining on the App because you only get automated Q & A's and there is no feedback and they still expect me to pay for the Cancellation Fee?
