Billing for cancelled subscription even though i provided the 30days notice as per terms

What postpaid service? I terminated the service in October and never used the services in November. I was billed and made the 30 days notice as per subscription. Which services did i use again. As of the 1st of November my services were terminated and i made payment in November, how is it that again in December i need to make payment???

Even if that is the theory used please enlighten me which services are outstanding currently? I did not receive any services in November since my sim cards were already canceled. When i paid in October i would have paid for services in September, and when i paid in November i paid for services received in October which was my last services as i had terminated. So which one's am i due for now?

You should review your customer services that does terminations, how is it that i should be held accountable because your staff failed to terminate d sim as of the 1st. U can clearly see the difference in usage from the previous months. I received a call from ur customer service on the 5th of November wanting to know my reasons for termination how is that im billed a whole R535??? and currently when i log on it says i have R0. 00 outstanding balance im still not understanding this billing? If you want to bill me it should be pro-rata due to the negligence of your staff that did not carry thru the cancelation for the 1st 5days in November. Which is the only reasonable explanation currently because i was not connected in November. Looking at all my previous invoices you can see that on average i used over 100GB however November the invoice stipulates 45GB. I followed the right process of cancelation why penalize me for something i did not use???

You are here telling me about an amendment because i complained, no acknowledgment of the fault on your side. You are still billing me for something that is not my fault, why ddnt you terminate my connection on the 1st?? I thinks lets take this to the comsumer Ombudsman because the level of dishonesty from your side with no apology, yet there is an expectation for me to just pay is beyond appalling. It had to take me this route in order to get a mere customer service, however i am still not being told exactly what transpired, im the actual person who gave an "Explanation" and you thought "Take it and ride with it" myb explain this to the Ombudsman then!!!
