Lost all confidence in Sanlam

Wanted to change my banking details and to increase my premiums for my retirement annuity for over a year now, generally I am not a patient person and I give up after around 20 to 30 minutes but waited almost 3 hours today (14:00-17:00) as I really wanted to make sure I get it done, I have been waiting for an agent before being notified that their offices have closed for the day, what a waste of time, I have lost all confidence in Sanlam, its now clear that we as customers are going to have a lot of similar issues if we want to make any claims, the only department that works is the sales team, sign you up, take your money and forget all about you, I have to now start all over with another company which is really inconvenient.
