Interest Rate Increase

I have two savings accounts with Capitec. One is a regular saving account, one is a fixed term. When the interest rates were increased last week I noticed that my rates were still the same. I emailed the contact centre and got a reply stating that has my account is fixed term the increase doesn't apply. Whereas I can see some sort of logic there - I still think the increase should apply!! But my main concern is my other account definitely should have had the rate increase app****!! I have responded to the original reply but have had no further contact from Capitec!! Could someone contact me and apply the increase ( retrospectively of course). I await a positive response!!
