Yesterday, I loaded 100 pesos, with 4 pesos still on my balance, then used 50 for the SUPERSURF50 promo. So I expect to still have 54 on my balance today. But when I checked it is only 34! Where did the 20 pesos go? I do not use this SIM to call/text, only for surfing. My SURFALERT is also activated, so how come there is a deduction? There was no notice given. Can I still get the 20 back? Or at least have an accounting of where the P20 go? Thanks!
