payment not reflected

I pay my municipal bill through the Erkhurleni website,my payment was made on 30 March 2015 and is still not reflecting on my account as of 9 April and I received FINAL NOTICE notification on my postbox today. I have also been billed a fee of R800 for delivery of aforesaid notice .It is not me who hasn't paid my bill, but Erkhurleni Web site that has not reflected this payment on onu account <br> Even though it is showing up as paid when I log into my profile<br> They are not updating my account timeuously <br>
