Poor service and Poor internet connectivity

Upon being moved from 4G to 5G It was promised that the network would be improved drastically and as such it was only the case for a number of weeks. For the past 2 and a half weeks I've struggled with internet connectivity and each time that the call centre / help desk is contacted , we receive a report back that the issue would be resolved within 2-24 hours. That's extremely dissatisfying as myself and my household need to work and we use the service for that purpose. One cannot call their help desk daily , throughout a week for help. It's costly and a tedious process.
