Double payment debited for months already

Rain is great when it's working but when there's a problem, especially with billing, it's impossible to sort out. Rain has deducted 2 payments of my account for months already. I've tried to sort this out from various platforms with no success. All that happens is that I receive reference number after reference number. This is extremely frustrating. You guys owe me a lot of money. Now I don't have internet because I refuse that you're debiting another double payment from my account. Where's your recordings? You guys promised me over and over that I don't have to worry, my 4G will be cancelled when I go over to 5G. This is not fair and not the way we do business.
