Nice Catch, Brother!
It is unfortunate! But if you are a little careful, you can avoid this scam. If you notice, you will see that they have also made many spelling mistakes on the payment page, which no such reputable company would do. As written below, it has been written, Transection has been written for Transaction, Confrom has been written for Confirm, Redix has been written for Redex. Moreover, such reputed companies never accept payment on personal numbers.
As a conscious user, I informed Robi and Bkash about this. I got a pre-written reply from Robi. I don't think they will take any steps in this matter. But a representative of BKash spoke to me. I don't know what will happen next. But they should be stopped. The one who gets scammed understands how it feels. I don't know how much money I lost in the new condition.
