Unable to Assist

I am very disappointed with the way i have been treated at the following BP Stations, BP Polokwane, BP Spruitview and BP Diepkloof . i have a BP fuel card that i have won on my discovery insure . it has R10, 000.00. and ever since i got the card it was a beginning of complains daily , firstly in Polokwane i was told that they receive their payment last and i had to pay cash after i had poured petrol , which i think this shouldnt be my problem , BP had a contract with discovery and how your payments are done i shouldn't be part of it. i went to Spruiview , the most rude lady told me they don't even know the card , its the first time they are seeing it. i then went to Diepkoof , spoke to the manager Gladys , she assisted me for the first 3 times and recently i have been told they cant assit me as they have a new machine and only gladys can operate it. i am not resorted to use cash whn i have a card that has money because your stations cannot help me, this is very ridiculous and unprofessional . if its a franchise you need to be uniformed and educated on the latest things that happen in the company. kindly have this issue dealt with the owners of the stations soon. its embarrassing
