RAIN IS HORRIBLE

Rain are really trying to **** me, I have been using their service since 2023 on a 4G plan, on the 7th of May 2026 I received the new router for 5G as I wanted to change for better speed, I was told that as soon as the new router arrives I should call and they will cancel it immediately and only charge me Pro-Rata on my billing date. Since the 7th May, I have been trying to get assistance and not a single person has called me from their retentions department, now they want me to be liable for paying 2 plans for as long as they can, I have called and the matter is forever escalated. I now no longer want to use any of their services, I want to cancel both plans and go elsewhere however they are still not letting that happen. I have 3 reference numbers already but nothing is happening. The only thing I can do at this point is to cancel my bank card and get a new one so that they dont deduct, surely I cannot be held reliable for their mistake.
