Complaint Regarding Unfair Invoicing and Service Interruption

I hope this email finds you well. I am writing to express my dissatisfaction with the recent handling of my account, specifically concerning an unfair invoice and subsequent service interruption. My usual monthly bill is R880, yet I am recently being invoiced an amount of R910 without any prior explanation. This discrepancy in billing is both unexpected and concerning. Considering that the past 3 months we have been constantly correcting their invoicing from over a thousand rands to the correct amount. In between this when the automated billing system debits it takes what is on the invoice and I am constantly having to rectify them. To make matters worse, my service was abruptly cut off, effectively forcing me to pay the inflated amount to restore connectivity.This situation has caused unnecessary inconvenience, and I believe it to be both unfair and unjustified. I kindly request a thorough review of my account and an explanation for the additional charges. Furthermore, I urge Rain to implement a more transparent billing process to prevent similar issues in the future. The past 3 months with rain have become such an unreliable space.
