Altering Existing Contract Pricing

Please note that i renewed my contract in January of this year to a Smart S + at R 199.00 with 200 minutes 200 sms and 500mb of data ,this is a legal binding contract ,you send me an sms informing me that you will be increasing my contract pricing as of the 1st May to R 299 with a mere 150mb of extra data for R 100 extra what a joke.

I do not accept this as you cannot please yourselves as and when you feel like it to increase my contract ,should you give me an extra 1GB on top of my current 500Mb i will gladly accept this .

Kindest regards Raymond Donaldson N **********
