Builders Card Call Center - Customers are not important

Called the Builders Card Call center: My main concern was that I was not able to make a payment via EFT. I called several times. On One occasion the agent stated they would call me back as were did not understand why I was not able to make a payment ( that way they could guide me through the payment process.

She said it should now work as there was a block on the account, which may have prevented me making a payment.

I did not get a call back, when callling again I was told that I must contact my bank, although the error shows that the reference number was invalid.

The call center agent then stated that the supervisor would not come to the phone as she was too busy with a query, When I asked if they felt that As a customer wanting to make a payment, my query was not important, I was told she was not going to come to the phone, as she had already spoken to me in regards to my query, and would call me back.
