Mobile number on file
So my wife lost her Cell Phone... these things happen...
( I don't like cell phones. ) - So my wife's number - is the 'official' business - contact number.
Then my laptop screen fades to 'Black'... and never comes back.
So - I fire up my 'Old' laptop... - the laptop I used to 'create' my account with BDC. - but for the last few months, I've been using my new laptop. So 'Security' Says - this is 'New' Device... 'We will text you a code'... ( Choice of only 1 number on file !! ) - no email option. - They also supply a 'Local' phone number that is wrong.
Then I get an email - warning me - that I have a booking 'arriving' that day...
I fire off an email - to '3 Different' people begging for help - to get a local contact number... or how I can get back into my account... - check-in date was 2019-03-09.
Thank you for choosing Booking.com and for being a Genius member.
My name is ||||||||||||, and I write on behalf of Booking.com Team. I would like to offer my apologies for the delay in our response due to a high volume of incoming emails.
I checked the communication between you and the guest and it seems that the guest stayed normally. Please let us know if you still need assistance to modify your phone or access the extranet.
I got the email on 12th of March.
So, the lesson is - make sure you have more than one mobile number on file with BDC.
