Serious Issue on Verification of Account while Sign UP

Serious Issue on Verification of Account while Sign UP

I am having serious problem while registering another account, I have tried all my phone numbers including my wife's own. it is not sending any code to the phone. the domain is aojfcc.org. the last number used is 09065848377 and my country code is +234. that mean if you are calling internationally, it would be +2349065848377. you can help me delete previous registration and keep the last one. Please help in the verification and if possible in the future to have many options of verification it would be nice, if one failed, one will go
