Poor to no network connection

I got my 5G router some time last week. Worked well until Monday the 12th of June2023, submitted a ticket via the app, that was ignored. . Called in and given ref number ***. Called in again today, the gentleman I spoke to could not assist. I pay for a service which I do not get. I now have to buy data because RAIN is always offline, when online I get speeds of up to 0.10 mbps. Being a client for less than two weeks but getting such poor service is not on. Already considering cancelling this thing.
