Double billing and promise not met.

This is by far the worst service I got from FNB Connect. I was billed twice today, for data bundle that are not even given to me. Checked my account balance I didn't receive the data. Called your customer help line and one consultant says the balance is there, that I should double check it; which I did and still nothing. The first time when I was being sold these bundles I asked when will I receive them, the sales person said the day the amount will be debuted. Well I was **** to. I expect good service and honesty from FNB, I have had my account since 1996. I guess FNB doesn't value loyalty from its customers. This is bad service
