Shell vplus rewards is a waste of time

This vplus sham is of what benefit to us seriously. I tried to purchase something in the garage with the vplus rewards card and entered the pin and the lady is asking me for otp which never came then when I try to call the helpline at half past 2 when the times the call center operates in till 3 they play a automated response that the times are till 3 and cut me off so did everyone at the call center just decide to finish early and go home. What a waste of time seriously and so glad that there is more options for filling fuel out here instead of getting bluffed with this sham of a vplus thing Shell is going on about because the people working at the garages have no clue on how the card works because it states if the card has a pin use the pin not a otp so I guess they took the money that was in the rewards card and I got nothing.
