I went to petronas as usual, I paid rm 50 for petrol. The staff swipe my mesra card and ask me to refill. After that, I asked for receipt and I check, there is no mesra point been updated. I try to ask the staff why NO mesra point, he just shouted at me says system down. This really frustrated me, because many times I face like this, this time I am going to complain. If petronas cannot give the mesra point, just inform me. I will change back to fill Petron better.
