VODACOM IS BUNCH OF ******

I have 2 contracts with Vodacom and have been a loyal Vodacom Customer for over 5 years. Today I accidentally opened my Vodacom app and I see my contract went up from R208,99 to R221,99 WHAT THE HELL????? I signed a 24-month contract with Vodacom for R208,99 how is it possible that this can happen? 2 months ago the other contract I have with Vodacom also increased from R299 to R308,99. IN CASE YOU HAVEN'T NOTICED WE WORK ACCORDING TO A BUDGET. It is more than enough that my insurance and medical aid go up yearly why the hell must my cellphone contract also go up if I signed a contract for 2 years? THIS IS RIDICULOUS!!!!!! IT IS A BREACH OF CONTRACT. If I don't pay my bill my phone is cut, but what can I do about Vodacom taking me for a ride????? I am sorry but if this is how Vodacom wants to treat its customers then I am canceling both my contracts and then I will tell the whole world what a rip-off Vodacom is. None of the other cellphone providers I am aware of is doing this to their customers. This is ****************, seriously, but be warned you are going to lose me as a customer. This was the last straw, MONEY DONT GROW ON TREES IN MY BACK YARD!!!!!!!!!!
