TELKOM MOBILE IS REAPING CUSTOMERS OFF

i have a contract of 2 cellphones which is payable every the 25th of each month to the amount of R538.00 samsung S4 mini for 2 years ending next year around may with the package of wifi, 100 minutes and data and what happened is they sent me an sms that reads: Dear customer for your convenience telkom will increase your monthly spend limit to 500.00 this will make it easier for you to purchase addtional data bundles or stay connected with friends and family just incase you deplete your inclusive benefits during the month. if you do not want spend limit to be adjusted simply reply NO to this sms within 48 hours.T's and C's apply.<br> <br> So my first question is they know very well that my package contract do not allow me to send sms and 2nd they didnt even bother to call to reconfirm if i agree 3rd my frustrations is that i had to call them to cancel this as i had not signed up for this i will only pay for my contract and thats it they dont want to assist me they keep saying they circulated the matter to the relevant department and now i have to pay extra 70 that i accidentally used withour noticing.i am very unhappy with them as i have budget i cannot pay phone R1000.00 if my minutes
