Q: i have had a new i phone and transferred my contacts to iclouds only this has put them on my moms iphone.  she has deleted them off her phone and so i no longer have my contacts as they have deleted off my phone also.  please is there anything i can do

You can only restore them from a backup. This has occurred because you are sharing an iCloud account. ideally you should each have your own iCloud account, that way you can each manage your own mail, contacts, calendars, documents etc and avoid unintentional deletions and unwanted editing. If there is information you wish to share between you, this can be done with a secondary account.

Having separate iCloud accounts, doesn't mean you have to have separate iTunes accounts, so whilst you keep your personal data separate, you can continue to share music, apps, books, TV shows, movies etc.
