Kicked out of WhatsApp

My WhatsApp account has been stolen and I have tried to recuperate it by asking for a new verification code, but I keep getting this message and does not allow me to request a code.

"You have guessed too many times.
Please check with your mobile provider that you can receive SMS and phone calls.
Please wait for a new code to be sent
Try again after -1 seconds

My phone works perfectly fine, so it is not that I am not able to receive the SMS.

I have tried to contact WhatsApp but I keep getting the same automated email with instructions on how to recover my account.

I have deleted and reinstalled the app a couple of times, deleted the cache in my phone's memory and waited over 12 hours to request my last verification code. And the same message keeps appearing.
