Infinite loop of account verification

Infinite loop of account verification

Hi I can't do anything on my zoho account.  I always get this message

Hi Sheriffo Ceesay
As a security measure, you need to link your phone number with this account and verify it to proceed further.

When ever I supply the details, it displays that the number is associated with another account. I don't have any other account on zoho so this is really annoying.
