Whaysapp of no use

I am a Capitec client and I saw on the internet that I can communicate with someone at Capitec on Whatsapp. I signed up but was disappointed to find extremely un-useful information. I thought I would be 'chatting' with a human but instead no real help. I wanted to know why I only get 2.5% interest on my savings account now it was 4% and what is today's interest rate for a single fixed deposit amount. The information on the internet is out of date and I dont trust it. Pity about the whatsapp 'chat' being pretty useless.
