Will never ever use rain in my live again even if it is the last wifi service provider

I have had rain for 2 years and then came 2025 and we start having connection trouble. When I call for assistance, they keep on telling me to move the unit and so we did. Then came March 2025 and we had such bad connection and when we have connection then we can only use one device at a time, so we decided that we are tired of moving the unit around and even that did not fix the problem. So, we decided to cancel our rain subscription on 1st April 2025 and that was such a big issue it took me 5 days to get someone to speak to someone as the app was not working even after deleting it a few times and reinstall it. I was told that the service will stop on the 30th of April 2025 and it did and i was told that the courier will come and pick up the unit 5 days after the 30th and that did not happen the courier called for pick up but was not at my home and said they will come back to me but did not so then I emailed Rain Quite a few times like 4 times requesting feedback on what is going on but to response to that email so I decide to do contact them via WhatsApp and up and to today the 20th of June 2025 I have not received any help from Rain even though I do speak on a weekly basis on WhatsApp and they keep on sending emails requesting someone to assist me but no response. Every time I get a call from rain it is the collection department wanting me to pay for something that I have canceled but no one is making notes or get this resolved. So, the unit is still with me and Rain are claiming I am owing them outstanding fees for Mei and now June and they do not stop even when I do explain my situation then the call gets dropped or like today, the lady told me that she does not care about my situation according to her I have an outstanding balance. So, Rain I do hope you get this complaint, and I get results as my next complaint will be logged at the The Office of the Consumer Goods and Services Ombud (CGSO) and see if they can resolve this as someone at rain is just getting paid but do not do their Job.
