Unable to Receive Verification Code for Purchased Microsoft Skype Number

I recently purchased a Skype number from Microsoft, but I haven’t been able to receive the verification code. I’ve tried contacting customer service at 0850 390 2777, but every time I call, the automated system hangs up. When I try to access support through the Microsoft website, I get a message saying, “Access denied. You don't have permission to access this page.” It’s incredibly frustrating that I can’t reach Microsoft for help, even though I’ve already paid for the service. What else do I need to do to get the service I paid for? I expect Microsoft to resolve this issue promptly and provide the service as promised.
