Being charged for 2 contracts when upgrading

Quote: ***<br> Order: ***<br> <br> I was notified that I was eligible for an upgrade on my account (6 February 2016) I then contacted the upgrade call centre (8 Feb 16) to process the upgrade and chose the Smart L package consisting of only data and airtime (No Cell phone). I was previously on Smart XL. I have been trying to obtain an invoice for work purposes and was shocked to see that I have been charged R2,101 for the month of March 2016. I contacted the customer care accounts call centre who indicated (after being kept on hold for 30 min) that I am being charged for both the smart XL and L packages. <br> <br> I indicated to the agent that I did not recieve the data and airtime for both packages and I was informed that I forfeited the airtime and data for the XL when upgrading. My question is then why did I not forfeit the Smart XL bill as well as I am being charged for services not rendered. <br> <br> I am now stuck with a R2,101 bill but I am on a R500 package, please note that I have no arrears and have been a loyal contract customer in excess of 12 years. I am quite saddened by this practice. Is this practice in line with prescripts and policies of the consumer protector?
