Absurd Service from R"nyain"

I have now almost 2 weeks without internet connection with rain. I've tried to change directions on their router to get coverage without winning. I called them to inquire about the " no connection " issue but they keep on promising the problem will be attended to. Sunday I called again they promised to send me a new device since " they had a lost connection issue " then mine didn't come back to get coverage. So I'm still waiting for the feedback since the 27/05/2025 . I have assignments to write, I'm attending session for my health everyday, I've used up more than what I pay for Data of "nyain" . My Sim cards were delivered finally after having a contract without having them. So either I get my new device before end of the week or I cancel my subscription with "Nyain".
