Hello @bajwaguri ,
Welcome to the community,
Every year bills increase due to the RPI/CPI, this year by 14%, some networks are charging 17%,, I presume that is what you are writing about, it is in the contract you signed and you should have been informed by letter from EE.
This has been largely discussed on the Martin Lewis show as well.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
