Avobuy In December 2013 I order 10 $100American Express gift cards from avobuy. Winmighnester ca Internet

On December 2013 I ordered 10 $200 dollars American Express gift cards from Avobuy they claim that it would take about 90 days to get them I kept calling them to make sure they were processing my order and every time they would told me that I shoul wait another 30 days cuz the bulk order had not arrived yet. Finally got tired of waiting and disided to cancel order. but they would not answer anymore. So I call my credit card to dispute the charge. They creditEd my money back and started the dipute 3 months later my credit card takes the money back saying that it was too long ago therefore I was without lack that I should dipute the matter my self. How can I do that if this crooks wouldn't even answer the phone. Can somebody help me plz. Thanks.         Efren    Lone Pine Ca
