Pathetic Service from FNB Connect

FNB has been taking my minutes from my voice bundles without me using my phone to make calls. I have 2 reference numbers 60540 (spoke to Siphesihle), last week an admin person called me to confirm my case. To date no one has called me back. I called in today at 2pm and spoke to a Manager named Mahlatsi, he promised someone would call me back at 4pm today. At 4.30pm I called the connect call centre again as I did not receive any feedback as promised by Mahlatsi. I then spoke to another manager named Whitney who had advised me that Mahlatsi has left for the day. My previous ref number was closed as an admin has already called me and advised that my minutes are correctly allocated. This is a lie as I have had no call as such. I am very disappointed in the way this case is handled. I had an issue not long ago about minutes disappearing on my other FNB sim card and was reimbursed, only to find out that FNB has been doing this for both my sim cards for a while now and I didn't notice until recently. I am completely disappointed that there is no accountability in these departments, no sense of honesty even though calls are recorded. I feel like I am paying for a service that is good to take your money, but not to follow through on their client's satisfaction on service rendered!!!!
