Lies from Rain internet provider

Have now been with Rain for a few months and have complained on many occasions about the disruption that I was experiencing finally they send a independent technician today 10 March 2021. So when the technician arrived I explained to him all the places I have tried around the house and having to reboot and and, then the technician takes out his laptop to check which tower is the closest to me only to find out that I was **** to by rain because I am not even close to the coverage of the 5G tower, as was told I was by rain. Then the technical person then reverted my signal to the 4G tower and told me to step down. After the technician left in about 4 hour I lost internet more then 5 times. So do we pay for a service that we do not have but given frustration with the lies and bull****. Hope to have this resolved.
