Unfare Billing

I joint DSTV on the 23rd January 2015 which was on a Saturday I paid the R399.00 package. Then two weeks after I joint I received an sms that my next payment is due on the 24th February 2015 I then phoned the call centre and informed them that I wont be able to pay the subscription fees on the 24th because I only get paid on the 25th of each month I then asked them to change the paying date to the 1st of every month. The lady at the call centre told me that she can change it to the 2nd because they don't have the 1st on their calendar which I understand but the lady then confirmed to me that I must pay R118 extra which I understand but she told me that I must pay the R118.00 in 48hrs from today (19th February 2015) I told her I don't mind paying but cant I pay the full amount at the end of the month she told me no and if I don't pay the R118.00 DSTV will disconnect the service which means I shall have to pay reconnection fees as well, but when I joint up the sale person who assist me never explained to me these things otherwise I would have waited until the 31st January 2015 and then connected my DSTV.
