Club Factory — order out of stock

Address:

East Khasi Hills, Meghalaya

I ordered a few items from club factory but One of my orders was out of stock as a result my money got refunded. it was not credited to my bank account but the money was refunded to balance in the app and it was written that I could either withdraw the money or use it for my next purchase.I want to know how can I use the money for my next order so I don't have to withdraw it
