Review GIVE MY MONEY BACK

I ordered some stuff in BO's COFFEE TAFT-LA SALLE

1 fruit tea
1 dulce de leche(slice)
1 muffin trio

After placing my order and paid it says that the MUFFIN TRIO were SOLD OUT and that they will refund my money. I have sent a complaint/message regarding this matter in the app but there is still no response. I am trying to look for any possible number that I can call them.
