GetPeso GetPeso.ph Rude Threats and total Ripoff Internet

I loaned at Getpeso. They approved it, but I was only able to get it after a week because the money transfer they made can't be found, I sent a lot of messages to them but they only replied to me once. I payed late because of some unexpected happenings but I did pay a week after my due however they are claiming now that they haven't received the payment. I sent them the proof I have paid already, but I'm continuously receiving harassing text messages. Very rude customer service. They have been calling me every hour, sending me messages every now and then. No investigation being done. They are just concerned of the money
