Extra charges is ridiculous

Generally when using Uber the price estimated is suppose to be the price I pay? Yes I can understand if there's traffic but lately the GPS of the drivers are giving them off routes allowing the trio to be way more than specified. Uber used to allow for this and repay ur fare as this isn't your fault noe they ripping people off claiming that we are not eligible for the refund. What bull is that. I didn't tell the driver to go off route and there was no extra traffic so why am I paying an extra R20. And this is happening continuously lately not allowing me to get my extra money back. Uber is making me want to use bolt or taxify since they are no longer the beater reliable transport. You also cannot contact support freely with issues they limit u to options. Uber u suck
