@ANNALARRIN If you do have itemised billing then that’s not possible. If you require itemised billing it will only commence from the date you request it it’s not back dated.
Your other options is to call customer services are request your SAR ( subject access request ) EE then have 30 days to provide you will all the information that they hold about you this will include numbers you have called and texted. You can not be charged for the SAR but EE could charge you for the admin work to gather this information.
