Sorry to hear that but the service is registered in Australia and has a good reputation.
Once bitify.com indicate that within 72 hours the refund should be received automatically so it should be, it's my money and I deserve to receive it on time
This rule will be canceled if the seller does not agree to the request to return the money to you then an investigation will be opened regarding your case.
All you have to do is provide more evidence and will respond to your request before the end of 30 days.
The investigation takes time because the product you purchased is software, you had to make a clear agreement with the seller before the request, such as if the seller did not respond within 24 hours the contract will be canceled, the correspondence must be made through the personal messages at that site.
If there is a rule like "refund money if the software is not installed" it would be refunded to you in a short time.
Do not be hasty, give all the evidence in a clear and vague way, add messages "PM" between you and the seller and solve your problem.
