INCORRECT BILLING

I HAVE RECEIVED ANOTHER STATEMENT TO PAY INTEREST - I REFUSE TO PAY THIS AS I DONT SEE WHY I SHOULD PAY INTEREST AS IT WAS NOT ON THE PREVIOUS STATEMENT THAT YOU SENT THAT WAS SETTLED. IN FACT SAIPA ALREADY OWES ME MONEY DUE TO THE FACT THAT I PAID R931.38 FOR RPL AS PER THE TRAINEE CONTACT PERSON.WHICH WAS PAID IN OCTOBER 2014 AND I NEVER RECEIVED THE OFFICIAL INVOICE, THEN YOU GO AND INVOICE ME IN 2015 SAYING RPL FEES IS R1000.00 AND THIS WAS NOT THE FIGURE GIVEN TO ME VIA EMAIL EVEN THE WEBSITE SHOWED THE FEE OF R931.38 WHICH WAS FOR 2014 YEAR BUT YOU INVOICE ME FOR 2015 RATES - THIS IS NOT FAIR. SAIPA IS FOREVER WANTING MONEY. I REFUSE TO PAY YOUR INTEREST AS I SETTLED THE STATEMENT FIGURE IN JUNE. I FIND THIS UNFAIR THAT SAIPA DEMAND MONEY YET I GET NO RESPONSE WITH REGARDS TO THE RPL FEE WHERE I WAS IVEN ONE FIGURE THEN YOU INVOICE ME A 2015 FIGURE. I NO LONGER BELONG TO SAIPA SO STOP EMAILING ME STATEMENTS. AS PER YOUR STATMENT SENT TO ME ON 11 JUNE 2015 THAT WAS THE FIGURE I SETTLED ON THE 12 JUNE 2015 AND YOUR INTEREST WAS NOT DISPLAYED SO I WILL NOT BE PAYING AGAIN TO SAIPA. PLEASE CORRECT THIS ASAP.
