Streamyx payment update

I pay my Streamyx bill using CIMBClicks. The first time I paid was on friday, I checked my bill balance everyday at MCMB (Multimedia Customer Management and Billing System) after the payment was made and the balance only updated after a week. I sent CIMBClicks a message asking about the slow updating, according to their reply, payment update is based on billers as for their side they have transferred the payment on the second working day after the transaction is made. Then I tried to pay on friday for one more time, same thing happens, it took one week to update the payment. But when I paid on monday, the payment was updated after 2 days. TMNet MCMB update delay for payment on friday...?
