Incorrect Billing

I am extremely disappointed with the service I have received from Rain. I changed my debit order date on the app and there was no warning that this change could only be done once every three months. I only became aware of this limitation after the change was already processed. I had already paid for December in November, yet Rain attempted to deduct again on 1 December. Despite sending multiple emails to resolve this issue, I only received automated responses and no proper assistance. As a result, my bill increased unnecessarily. I am currently on a month-to-month package, which is meant to be pay-as-you-use. When I refused to pay for incorrect charges, the service was suspended. However, I am now being expected to pay for January even though I did not use the service at all. This is unacceptable and feels like unfair billing. Month-to-month should mean that if payment is not made, the service is suspended — not that customers are charged for periods where no service was used. I have been a loyal Rain customer, but this experience has been extremely frustrating. On top of this, the network quality has declined significantly, with poor connectivity especially during cloudy or rainy weather. I request that this matter be reviewed urgently and that incorrect charges be reversed.
