Dishonesty, *******

In all honesty they don't even deserve a 1 star. here's why, So I have been using Uber for a long time and needless to say that has come to an end. On Saturday evening my boyfriend and I wanted to get an Uber to get to our destination which was 7 minutes from my house. I had a 10% promo on my account and Uber wanted to charge me over R150.00 for a route I used to take on a daily bases which only costed me a little over R65.00. Please tell me how?? with a F***ing promo is costing me over R150.00. But when i look at my boyfriends phone Uber is charging him R79.99 and that is without a promo to the same F***ing destination. Now the night has come to and end and we want to Uber back home, Again on my side I have a 10% promo and my boyfriend doesn't. Uber wanted to charge me over R250.00 for a 15minute drive back to my boyfriends house.... but on his side they are charging him R115.00. can someone please explain that to me, because from where I am sitting that is complete and utter Bull***t. How can you give someone a promo discount and still charge me those prices... this is ******* on another level.
