Poor customer service

Actually I'm quite sad 😔. I tried to create an account but its denied my details. I put in everything correctly and I double checked it I tried over and over again, no other platforms do such a thing at the registration. I even sent them 2 or 3 emails to assist me, they take days to respond, and they take days to call me. Most of the time they call at the inconvenient time and sometimes when my connection is too poor. I also informed them all of that in my emails, which is where I communicate effectively. I don't what wrong with them it either they don't want to understand me or they are not good in dealing with clients who have technical issues with their platform.
