Bad 5G connection

Switched to 5G home basic from the 1st October and it has been a nightmare. Called to complain about the slow speed and bad connection. Have a million reference numbers from all the call logging with an unresolved issue instead you receive an email to rate the service. False marketing of this 5G as you hardly reach 15 mbps and otherwise the connection simply cuts out. Best part is that I'm less than 1km away from the 5G tower. Regrettably choice I made and wouldn't recommend it.
