Rain Mobile network provider company Failure to connect to internet or help

Rain has givine me such poor customer service and poor network connection. I have had the 5G home wifi for almost 3 weeks and the network is always down. I have called and messaged the Rain Mobile network provider company so many times to resolve this and all they do is send me messages that they will send a technician to check which has never happened. The speed is very low and never works. A total waste of money and waste of time as i wait on that call long only to be disconnected. Very disappointed, as I work from home and need internet connection.
