Our bill for last month arrive amounting to 76,000 thousand peso. The guy who said he would take the letter to it back to check with the company. Then this month we have a letter of connection from them amounting of the same 76k with an added amount 330 peso only for this month bill.

Our bill most of the time range from 400 to 900 peso. To thinks it only water bill.

What should we do with this? Anyone encountered the same problem?
