BASH, TFG ORDER CANCELLED

I have had a better experience with TFG Online shopping (Bash), until I made an online purchase of Jonathan D Tan franklin Loafers and made a payment. I tracked my order and everything seemed to be going well, but then I received an email saying my order was cancelled as they did not have inventory available. I am not happy with that as that was a bargain. I looked up the shoe just now and it is available. I feel that they should have postponed my order instead of reversing my account payment, or a least communicated that with me. I AM UNHAPPY. Other than that, I have no other complaints.
