Premium not as per pre-agreement accepted

I requested a breakdown of the bond repayment from *********** as i noticed that it was higher than what i recently signed for at the attorneys and received it. I then sent the quotes I received for the credit life cover prior to signing at the attorneys to the same e-mail address *********** and have not received any response. I have been following up but no one has come back to me. Please see below e-mails.

The amount I was quoted for assurance premium on the pre-agreement was initially R292.72. This is what i accepted when i accept the bond. I then noticed before signing for the bond at the bond attorneys that this amount had increased to R318.92 And was told that the amount increased as it was calculated on the total amount whereas previously it wasn't. Now a month after signing at attorneys and debit order must go off the premium is R454,53

Please can you urgently assist in ensuring the premium for credit life is amended as per the signed quote as the debit order is supposed to go off on the 15th.
