Rain very poor customer service

I am still waiting since May for Rain to investigate, respond and give me back my money back for April whereby I was billed for internet service I did not get for a whole month because of their towers failing. The audacity for billing me and then not wanting (I have reported it several times and I have received no response just that it has been escalated that’s all which was 2 months ago) to give me my money back. Like I have never been this disrespected by a service provider ever.
