Worst experience ever

I have been trying to call Finchoice to update my contact details on the system without success, the first two agents advised me that they are unable to assist because I cannot confirm my home address that they have on the system and cannot be put through to a supervisor for the same reason. I then called the third time and an agent was able to assist me without confirmation of my home address as I was able to confirm all other security questions however she put me on hold and phone was hanged up, no one has called me back. All I want it to update my contact details I don’t understand why is it such a hustle to be assisted, I spend almost an hour trying to get this sorted and after all that it’s still not, can someone call me please to assist me with updating my contact details. This was the worst experience ever
