Hello @24535783 ,
Welcome to the community,
You do not say what phone you have and how old it is.
Have you tried rebooting your phone? Have you made sure that you have not set the volume too low?
You may need to factory reset, but make sure that you back everything up before doing so.
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.
