Bad service

What a **** service I recieved from BP Tshepisong. Iam utterly disgusted, I bought BP petrol voucher on vodacom app 24/08/2022 got the voucher that i can use to redeem. I went to the BP Tshepisong garage to use it, it was accepted by the speed point, the attendant did not pour the petrol saying they do t know who to capture the sale on system. Fair enough I left and asked them to call their head office for assistance the next day and give me feedback to come and pour later. I called them the next day to follow up I was told that they were asked to email the sale receipt. Which the didn't do. Saturday 03/09/2022 I went there the Forecourt supervisor Thulani told me that he can't take my query cause he does not want to be responsible for it as he was not there on the day of incident,even after I guided him on what to do. Asked the the garage manager they call an arrogant fat Magin buu Nhlanhla who told me straight on my eyes that they wont do any thing I need to call their head office , I was shocked and told her that I am a customer who need their service I am not their Staff. I called BP as instructed by her they told me that they BP Tshepisong need to send the receipt to the help desk. Is this the service to BP give to customers😡😡😡😡😡
