inContact Details not changed by Fnb

I had to recently change my cellphone number and have been going backwards and forwards with Fnb to get my details updated with them. Premier banking was unable to assist. Then after numerous phone calls I was assured my cellphone number was changed everywhere. I even received an sms to confirm the cellphone number change and that inContact had been updated.

Yesterday, I swiped my card for more than R100 but I did not receive the sms for inContact to notify me there was a transaction on my account. How is is possible that my number was changed everywhere but I did not receive the message for inContact.

Please can this be rectified as it is impossible for a client to be assured their details are updated but they do not receive any notifications when transactions are made on their account. What is the purpose of inContact then.
