Billing Issue

I am writing to bring to your attention an issue with my billing. I have been overcharged by Rain and would like to request a refund promptly. Under my name, I have two subscriptions, one of which was for 5G premium. I terminated this subscription before the end of February (February 28, 2024). However, despite the termination, Rain continued to bill me, resulting in a total charge of R1,452.58 at the end of March. I have already reached out to your call center and spoke with a representative regarding this matter. Unfortunately, I was informed that your system does not allow customers to provide proof of termination or dispute charges. The representative also mentioned that the account is charged after usage. I want to clarify that my Rain Premium subscription was not utilized at all in March as it was terminated in February. Given these circumstances, I had no alternative but to resort to social media channels to seek resolution. My reference number for this matter is Rain853293. I kindly request your prompt attention to this issue and appreciate your assistance in processing a refund for the overcharged amount. See attached screenshot for further information.
