Mweb fibre price increase to keep 25mbs/25mnd

I am very unhappy with Mweb Openserve Fibre, i bought a 12 month contract for 25mbs/25mbs for R499. It has only been 7 months and they are already moving the price up with R100 if I want to keepy 25mbs/25mbs. That is not acceptable as my contract states that R499 is for 12 months. Cant wait to find another fibre provider that keeps to their word.
