For your information, there are 4 credit card Maxis Center accept for installment plan.(Public bank, Maybank, citibank and HSBC). So far, i only know HSBC and Citibank is 0% interest and no processing fee. If maxis do impose processing fee, you can put up a complain to bank negara or to the credit card itself on the merchant.

But those using Maybank and Public bank credit card, i not very sure. Before put booking on Maxis Center, please double confirm with the person incharge working there own the merchant machine for HSBC, Citibank and Maybank. Public bank, i think u need to fill up some form.

I heard that conversation on maxis customer service too, but i did ask Citibank and HSBC customer service said "merchant are not allow to impose any priocessing fee on 0% instalment payment plan and if the merchant impose processing on your payment, you can actually put up a complain to us (Citibank/HSBC) or to Bank Negara".

For Maybank and Public bank credit card, i not very sure. I suggest you call up your own credit card customer service to clarify about the interest and processing fee, before you do any transaction at maxis center.
