Presumably when you signed up the price was acceptable, and the increases are part of the T&C’s ( so your current price shouldn’t be a surprise to you )
As someone comes to the end of a minimum term , they are in quite a strong position , they could ‘negotiate’ and chances are you would get a price similar to that offered to new customers, or they could leave for someone else, it’s always a shock to realise that someone is getting the same products or service much cheaper , but it’s the same as if you bought a TV ( and we’re happy with the price ) and a few months later noticed the same TV at the same retailer was for sale, hundreds of £££ cheaper.
What no ISP does , is sign up a customer , and guarantee that during the minimum term the monthly price will fall , if the offer to a new customer is less than what you pay, if an ISP say £60 a month , but reduced to £30 for the first 24 months (£60 after that ) it’s to encourage signing up to another minimum term at the end of the first one, but the £30 isn’t fixed , it’s subject to the inflation based increase.
