Rain, Lack of Lervice & Ethics

I've been with rain many years. Initially we had no problems, after a year or 2 we started getting erratic service. For the past few months we had endless downtime to which they said they're busy with the faulty tower in Lenasia. We had to buy airtime as a much needed backup, even after requesting that they credit us for downtime they ignored. Almost everyone in my area are canceling. The other thing we noticed, for a while now, even though we prepay for 30 days, few days before the 30 days they debit your account, so when time came to renew my card I did not. This is when I realise they've been suspending services yet there's still a few days to go. So now I've canceled as soon as they cut off services & returned the router the same day. I canceled online, had many dumb chats with their Ai BUT they are demanding payment for next month. This is on spite of us repaying & been suspended about 4 days before my 30 days which was prepaid & also in spite of their Lenasia tower being down at that same time. How ironic, EVERY time it rains, rain does not work! I owe rain NOTHING, in fact they owe me. I want a statement saying I owe Nothing, 0 balance & I want them to stop harassing me, spamming me on whatsapp. I have records of all chats, people spoken to, proof of router return & proof of all payments etc. It's insulting when Ai tells u your account is not in good stead. I've been a loyal customer for some years, only when I realise the dishonest timing of their debits did I not renew the card so I could control it myself, yet they still cut off the service with few days to go. Rain has really dropped below par in every way. They have frustrated me enough, I owe NOTHING!!! If they continue demanding ANY money I will proceed with legal action & make a concerted effort to get my voice out on ALL social media platforms. There are too many rain clients with the same complaints, I think rain has to be investigated. I WILL go all the way if I have to!!!
