I have 2 devices for myself and took a phone out for a family member, as they are late with payments and i am forced to pay as it is in my name, is there any way possible in changing the owner for just their device to their name... ?Thanks in advance...

I have paid my bill manually as i dont have direct debit set up, i paid this a few days after my billing date, will i be charged again on my due date or will it take the money off and not charge me again.Thank you.

Just want to ask if it is possible to change my airtime plan as i have paid the device plan and hiw do i do this. Any help woild be appriciated
