Pathetic : Contract Charge Increase and not notified

<p>I was on a Package for R199.00, The contract then Expired and i was advised telephonically , that i may continue with the contract at that price, Last year Jan 2016, the price was increased to R299, I WAS NOT ADVISED OF THIS !!!!!!! I have since cancelled the contract due to the lack of Principal, However I need to be refunded from last year 2016 to date of cancellation - Feb 2017, Please refund me, as I find this totally *********!!!!!! I have recommended and sold your network based on excellent service, so so many customers, this is really dissapointing!!</p>
