Terrible user experience

Wow.. such a bad user experience! I had a Pay U account from. few years back. I was having trouble paying with my credit card for an online purchase, and the only other option was PayU. I tried logging in with my details - didn't work. I tried changing my password - didn't work. I tried making a new account, only to be told that my email address is already in use.. so I tried another email address, only to be told that my phone number is already in use. I can't spend more than 45 minutes trying to make a purchase.. so frustrating!
