Agreed a conract with them for 2 years £55 p/m. Then 7 months in they suddenly decide to charge me £64 p/m and there is nothing I can do about it. When we enter a contract it is to lock in a price, why else would a customer sign a contract? You may as well be sim only. If my mortgage or utility company suddenly decided to change my price mid contract there would be uproar, well O2 can do whatever they like, and tough if you dont agree because its in the small print that you never read. Im stuck now and im furious with them. Tell as many people as you can to NEVER sign a mobile phone contract. You basically just sign all of your rights away and have to pay whatever O2 want to charge. They could increase the price to £700 p/m and I would still have to pay. As a customer you gain nothing from signing a contract. Never again. We should all join together and stop this company from ripping off their customers.
