Hello @Simona24 ,
Welcome to the community,
You should receive a text from DPD letting you know when the delivery will be and also on the day of the delivery with a one hour delivery window, but you will then have the opportunity to change the delivery time.
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.
