UTTERLY BAD SERVICE

I have been with FNB for more that 20 years, never missed a payment or even late for a payment. I have send in my application on the 1 July 2020 to increase my bond-total value of bond would be less than a quarter of the value of my property. I received an automated SMS, to say it has been send to credit. Since then no communications, my so called "Private banker" telephones is always to voice mail, and you can leave him messages, no response or any return phone call. If trying to phone the contact center, they refer you back to your private banker, which never came back to you. You would think that in this Covid19 crises, that a bank that promises to try to help you, would have the courtesy to at least contact you. IT IS THE WORST SERVICE EVER, AND THEY ARE MAKING MONEY ON EACH AND EVERY TRANSACTION
