SOS Squad charges more than the advertised fee

I have contributed to SOS Squad for a number of years. I have never used the facility and been unsure of how or what they cover - the membership came into being when I signed up with Netstar. Today, I called them to cancel the membership. The call centre agent was incredibly friendly and named some of the services on offer before she cancelled the membership. She also suggested that I look at the website for additional services offered. What I found is that I have been overcharged! The website states "Have full access to all the assistance you could possibly need with reliable 24-hour support. Only R55 per month". The FAQ's state, "How much does SOS Squad cost? Premium, unlimited access to all SOS Squad benefits are available to you for only R55 per month." The terms and conditions state, "Changes in price: We may change the price which you pay for the Services from time to time. In particular (but without limitation), we will increase the price by a reasonable margin on an annual basis." No where does it state that members who have been paying for their membership for years, pay more than the advertised fee. No where does it state that the fee is FROM R55 per month. It clearly states that the membership fee IS R55 monthly. I find this outrageous. I have been paying more than the R55 monthly. The membership and the difference may be small in value, but it is the principle behind it.
