That's sounds like a French philosopher's question, to which the obvious answer would be "If the mobile has been destroyed, how do you know they keep calling it?"
But, if you'll excuse my self indulgent humour, you've presumably bust your phone, what do you now want to happen? Forum staff can help with the problem, but only if you explain what that is. Are you seeking to cancel a contract, to claim on insurance, change your contact number, or get a new SIM card or whatever?
Any personal details (eg phone numbers) can be given to staff members by private message, but if you can elaborate what you want first, then they'll pick up your post and advise.
