I have a complain about intellicell.They deduct my money without my concern or permission.The last time i spoke with them they said i have to send them my 3 months bank statement and proof of imployment then when they bring the phone they will swipe my card for debit.i didnt send them my 3 month bank statement and proof of imployment.to my surprise i got a notification that they deducted my money, i dont know how.I want my money back as soon as possible. I only gave them my account number as the consultant said it is the part of application process.Daniel ****o sebola .
