Not happy with Vodacom

So after receiving this very upsetting sms from Vodacom that my contract premium will be increasing i was really annoyed.I then decided to call to downgrade but after hearing that there is a penalty fee to down grade my package from 100 airtime to 50 airtime was absolutely ridiculous. I was told I would have to pay an amount of R550 odd to have someone click on the pc to dowgrade my two contracts. Honestly I think this is sick of vodacom. We pay monthly fees for service but as soon as we want to downgrade they quick to suck money out of customers! !!!horrible!. I also spoke to a friend who is with cellc and during his contract the prices have never increased but I see that is different with vodacom.you make rights in just increasing the premiums. Really horrible. Once my contract is finished next year March I will no longer want to use vodacom.i will rather use a reliable service provider. I have afeeling most people are not happy with this so i know i am not alone on this
