Never received sim but debits are going off consistently

I never received the sim yet every month i'm being debited for data. I am not sure if they can't see 0 usage on the sim they're debiting for. Anyways. I called so many times, calls never finish, i wait and calls drop mid verifications etc, no one ever gets back. Not very good customer service, since 7am this morning i have been taken from pillar to post, given this number to call and that one to call. Have no choice but to share this review.
