So I filled up 98 unleaded tonight. Went inside to pay and tried scanning the voucher. The guy tells me that there is an "internal server error".
I asked him can I try paying through the app with the money loaded into the account. Payment went through no problem but voucher was not applied.
Could not believe the ridiculous excuse, how can the payment through the app go through fine but the voucher gave an internal server error?
Sounds to me like a poor excuse for denying a fuel discount especially the fact that I had filled up already and basically at this particular petrol station because of the voucher. Not to mention the Liverpool 7 eleven never ever had any stock on free items in the app.
