Contract Migration Mess

In September, I decided to get Telkom's Uncapped LTE deal. I was an existing customer and I wanted to migrate my existing contract to the Uncapped LTE deal. <br> <br> As per the terms on their website I filled in the online application as this is the only way for existing customers to migrate. I was contacted by the sales consultant and I informed him that I was an existing customer who wished to migrate. I was informed that a new application would need to be processed and that if the application was successful the old contract would be cancelled. Everything went smoothly till this point.<br> <br> One month later however, I am getting billed for both the contracts. Each time I call the call center to query this I get told a different story (I have been told that calls have been logged for the cancellation, that I app**** for the service as an additional contract, and that I was not eligible for migration despite the terms on the website).<br> <br> To date the original contract has not been cancelled and nobody is able to assist me.
