Hidden fee from customers

I have been a loyal customer of Telkom for the past 2 years. As my contract was to end their service provider called me for an upgrade. With all discussion we had never been told about any other fee that I will pay it was stressed that will continue paying the same amount as I have been paying. Received the phone on the 30th October, and surprisingly been prorated for the 2 days before the end of the month. I called several time to resolved the matter no one is keen to assist. It's unfair how they treat their loyal customers. It's real ridiculous. I even asked the recording which I received nothing mentioned about me paying extra cash.
