INCORRECT BILLING

<p>Once our 100GB limit had been reached , my husband called Telkom to buy an additional 20GB for R100 . The Telkom representative stated that he would load the top-up. When we received Feb invoice, the extra 20G had not been loaded and we were charged R451.68 additonal usgae. How is this possible when once our monthly limit is reached, the inetrnet usage is cut?! We tried to call their accounts department numerous times but with no luck. We emailed an account billing query but have not had a repsonse since!!! We need to resolve this urgently </p>
