Checkout.com interview questions

A few years ago I interviewed with Checkout.com at London. I was living abroad and I let them know my phone signal was very bad, but still, they decided to keep the technical interview on a phone call. During the call I mentioned several times I was struggling to hear and understand the questions, the recruiter ended the call and I wasn't moved to the next stage, they said I didn't have cloud experience, which wasn't true. Their recruitment team has contacted me several times over the last year asking me to do a first interview and, apparently, when they come to know about my first failure, they will never even arrange the first interview. They will say that I'm not fit for the role anymore, the role is closed, or any other excuses. Worth mentioning that I've never applied myself, I was always contacted on platforms like hired.com or cord.co. Their recruitment process is absolutely unrespectful and a waste of time and effort.
