SOS Protecsure now National, would be nice if their clients were informed

I found out by accident that SOS Protecsure was taken over by National. It would have been nice to be informed that on 1 May, an extra 8% and a R10 fuel levy would be deducted from my account by National but why should clients be informed. I found out through facebook and my new debit order coming off my account without my knowledge. I tried to contact National today and spoke to Candice Soobramoney who assured me someone would contact me from accounts department because the phone just keeps repeating "you are important to us"....really? I need to find out why if National has already taken my money, why did SOS invoice me also, do I have to pay double for something I don't want? But no surprise, no one called me back...because i am a valued client...not! I have now cancelled and joined a different security company...pathetic
