Price Increase March 2026

I need to make a formal complaint; how can I do this?
Why has my membership fee increased?
When does the membership fee increase take effect?
What is the CPI price index percentage?
Does the new membership fee reflect my discount?
Does this price increase affect my current contract length, end date, or upcoming freezes?
Can I cancel my membership because of the membership fee increase?
Are there any alternatives to cancelling, such as extending my contract to obtain a lower rate?
