I have been struggling with the customer service since the the month of May 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 phoned, I have emailed, I have really tried to get this sorted out, with countless replies which I don't get any assistance. Please can anyone assist as at present my query has been escalated to their technicians 6 days ago but I am still waiting.
