Uber Rides are *******‼️‼️

Everytime I book and take a ride with Uber, I “supposedly” get a discounted price. However, with a few hours, they the deduct the original charge, I.e R69, then then immediately reverse the change, but only reverse R51. This is theft, dishonest and advertising lies as they have now recovered their original charge. This action of theirs has been going on for a while now. I want my refund of all the over charges reversals
