Question for Meralco - Rosario Branch

I pay my meralco bills in SM Rosario Bill Payment together with all my others bills. This is my regular/monthly routine in paying my bills. but all of a sudden I received a disconnection from Meralco yesterday, August 15. It so happen that I can't find anymore my proof of payment. What action we need to do in order to trace my payment. I also tried to call SM, but until now their contact information is not working. Please help
