Fibre rates gone up by R100

It’s not even a month since i used Mweb fibre but im complaining. Their rates have gone up bu R100. Flippen Hundred rands and np communication was made to me in regards this. I was shocked to see my next month’s statement. Then we’re expected to agree?? It’s the 15th today and i get a statement saying on the 25th R100 more will be debited on my account?? This is honestly oblivious and inconsiderate. Next thing when you cancel they you tell you you're binded with them for a year cz you cz they gave you a free router.
