Rain Cancellation that is not coming to an end

I have been trying to cancel rain since March and every time the cancellation doesn't take effect. On the platform online, whatsapp I also sent an email which has not been responded to. I checked in again they say it's not cancelled. I was advised that the billing period must pass then the cancellation will take effect. I incurred then the charges for April, I then cancelled subscription on the online platform in Apand did as they advised and they explained that by the end of April it will be cancelled. I am now being told that the cancellation has been locked in yet which is why I was charged for April and May effectively. I am sorry, I do not have money to give away to this thing any more, I am struggling to even make the payment arrangment that they said I should do. And also if this is the problem I will keep encurring then I cannot pay for it as I already don't have the funds for more charges. your urgent response is greatly appreciated. my number is ***
