Can't even access my account

I have been struggling with the customer service since the 25th Feb 2021, I signed up for a lotto account years ago, and have not accessed it for quite sometime, since signing up my number has changed and I do not remember my password, so I cannot sign in. If I click "forgot password" it wants to send an OTP to my old number. I have phone, I have emailed, I have really tried to get this sorted out, with countless replies of

"Thank you for your email.

-our request has been escalated and put under investigation and feedback will be provided within 72 hours

Please feel free to contact the Player helpline on *** should you require any further assistance. Our team are available Monday to Saturday 6am to 11pm, or Sundays from 6am to 9pm.

Regards" but never actually getting a response after that. This is really ridiculous.
