Telkom's Billing ****

I did a new application for a smart device with Telkom on the 11th of October 2015 and my new phone was ready for collection by the 16th. I was then advised that the first premium / debit order will be going off on the 20th of November 2015, on which I agreed to. I then asked is there any amount I will need to pay upfront?<br> I was advised NO. On the week of the debit order, about 3 days prior, I was sent an sms advising that I need to make a payment of about R1371.43 and an amount of about R320.00 avoid suspension of my cellphone services. I then called their contact Centre and asked about this added amount on the contract I know nothing about, was then advised that it's amount from previous contract. I disputed the fact that how do they add an amount of a cancelled and paid up contract into a new contract. I find it ABSURD that an old contract can be added into a new and which the old one was cancelled as I had sent a request, but to my surprise that was not done. Now they need me to pay for something I know nothing about and I'm not willing to waste my funds on ****ty service and not as per the agreed terms and conditions of the cellphone contract.. this mess must sorted out.
