Help Desk is no USE at ALL Can't even Resolve a Simple Cell Phone number Change

I Phoned Truworths and was placed from one operator to another after wafting for more than 30 min and still no one resolved the problem i hang up they don't take in consideration that it costs Air time that they don't replace for you just to change the number where the OPT must be send. I have been a Loyal Customer for more than 2 years and this is the treatment I received
