Bp mistreatment

Hi my name is Malebo Augustine Mahabo I'm a paralegal practitioner by profession and a Bolt driver and partner. On or around 16h50pm 20/01/2022 I went to Protea Bp petrol station for petrol. I was attended by a lady by the name lufuno which i politely asked to help me with R70 95petrol with a R200 note , to my surprise i notice the lady to have gone beyond the required amount and the dispute started. Seeing that we don't find each other with the lady I asked her to involve her manager which I was told was on the phone instead to go explain what happened to a teller only to be ambushed by both Bp colleges that i have planned to Couse drama and as I told both workers I'm going to escalate this issue I was told I'm not going to even get my change which is also my customer's change as I have asked my customer to fill up with her R70 ride fee. All expected was a I'm sorry for misunderstanding how can we resolve this issue. Please help helloperter as you are known to be helpful in this type of matters. Thanks.
