Customer Service Complaint, Account Blocked

I registered for a PayFlex account this Monday, 28/10/24, I was redirected to your site to create an account via the merchant site I was using(Woolies). When I tried to login thereafter, it first sated my password was incorrect, on second attempt, it stated I was blocked. When I access your site or login in app there is no issue, however I can't make purchases with my details. I am a new customer therefore have little knowledge regarding how the company works. Why am I blocked, you chat bot states I did not make payment in time, but I have never used the services. When I call, it's states no available agents or number is busy. I sent an email on the 28th, 2 days later I have not received any response. I came to here to better understand how your customer service teams works since I am unlucky to reach you in all aspects, only to find the company actually responds to complaints. I am therefore writing a complaint as I would appreciate getting assisted with my query and for my account to be unblocked
