Price increase on existing contracts in poor taste

I am an account holder, ***. I moved from another provider because vodacom offered a nice deal on blackberrys, this was 2 years ago.. I upgraded end of last year to a smartphone deal that was nice as well.. Since then rumours came that contractfees were to be increased by vodacom.. I felt ok as I thought it will only be applicable on new contracts, however, to my disgust Vodacom did so on existing contracts too.. I now have an increased premuim on 5 contracts I have with them.. This way of rewarding faithfull users leave a bad taste in the mouth and I am sure that in future this treatment will play a big role in pushing me back to MTN.. Shame on you Vodacom.. After all, I guess you dont care as you have grown so big now, that my bark wont even be entertained.. This leave me with very little pride in supporting you, so you can be sure I will be one of your biggest \NO TO VODACOM"campainers in future.. """
