Rain is taking customers for a ride

I subscribed with Rain and paid the month-to-month fee (6th to 25th PRO-RATA) on the 6th of Jan 2025; the router arrived Friday the 10th of Jan. I was not happy with the slow internet; I called several times to report it, but no change. On the 15th, I canceled got a confirmation email, and that logistics would contact me to fetch the router. The router was not fetched, and I was billed for the 25th of Jan to the 25th of Feb. I called to enquire why I am billed when I was canceled on the 15th. I was told a lot of stories and they are saying they will only fetch the router after the 25th of Feb. Now I have to sit with a router which is not working while Rain is eating my money. I need my money urgent so I can buy data to work. Rain seems not to be interested in refunding me ASAP since they are the ones who made the mistake of billing me when I canceled 10 days before the 25th of Jan.
