So it's been a whole week of me calling mrp to find out why i can't login to my my mrp app or even online evertime i want to login it says email has not been authenticatioted this is my pin and email that i use since i open my account and suddenly i can't login and place an order our nearest mrp is 200kil away that's why i like to shop online evertime i call they keep on sending me this emails to reset my pin wait 24hours and still it's the same problem yesterday i called 5times and some of them were so rude they hang the phone up in my ear thinking of closing this account what's the use of having it when they can't help you I'm done and really disappointed
