****med on the bolt app

So what happened to me was I requested a ride specifically 5km ride only to be charged an extra money and be told my fares were recalculated, when I ask the so called support team by the name of Dolapo he or she is unable to explain to me how and why fares are being recalculated during or on the trip. My driver asked me to show him my app and was busy with my phone for what I don't know and he even mentioned that it's difficult to get a refund when using card payment. Meaning all bolt drivers are aware of the ****ming deals happening on this app and we loosing our hard earned money just like that and this bolt team are not taking us seriously. They know what they do and it's not nice at all. Bolt should be accountable for our lost money on their app.
