FNB IS REFUSING TO RELEASE MY NUMBER SO I CAN PORT OUT!!!

A few years ago I signed up to FNBConnect and ported my number to their line.After a few unresolved issues with my bank account,I decided it would be best to move from FNB to Telkom to mitigate future disasters.I have been trying to port to Telkom for the past 3 months and sent from pillar to post because FNB REFUSES TO RELEASE my number so I can port out.I have dealt with more agents than I care to and have had to drive to the branch numerous times with no luck.After a bit of research I now realise that I am not the first or only person to ever experience this.My last call with an agent revealed that they cannot port out numbers.This was after 45 minutes of the agent going through the process of cancelling my contract and reassuring me that it would be done .I have not been able to buy airtime or data on my sim and this has endangered myself and my kids on more than one occassion.FNBConnect is a disgusting service provider and i regret having signed up
