Welcome to the community!
Thanks for the information!
It's unlikely that the call you received was actually made from that phone number. Since the spammers/scammers use spoofed numbers, it is not possible to identify the true spammers' number. Mobile providers and landline providers simply cannot block a number without absolute proof that the owner of the number is engaged in nefarious activities. If the spammers chose to spoof your number. I think you would agree that if they blocked your number simply based on its apparent use to make SPAM calls or send SPAM SMS, you would not be impressed.
The providers have implemented Universal Call Block which only blocks calls from malformed phone numbers. Hopefully, the new protocol STIR/SHAKEN will help prevent nuisance calls from spoofed numbers. However, that system is not yet fully implemented.
Hope this helps 😀
