HANA Trial on-demand account - Stuck with my phone number verification screen

Hi,

Can anyone help me with the following: When I logged into my account.HANA trial.ondemand, I was re-directed to the phone verification URL and I was asked to enter the phone number to get the verification code. I tried getting the verification code by pressing the New code button but I didn't get any message, after 5 attempts I was unable to proceed, so now I can't proceed into my account, so it will be harder to complete the SAPUI5 WebApp Dev course on open.sap.com

Can anyone help please. (Note: The Phone number is incorrect)

Many Thanks,

Luis
