I understand your point and I also appreciate all the effort you put in creating your software. You are a very talented person indeed.
From our point of view, when we purchase a product we expect it to be working from the start without any further hassle and waist of time and resources for our business. As I mentioned before we wouldn’t be able to grant you access to our website due to internal policies and data protection/privacy.
Please note that distance selling regulations and consumer rights entitle us to refund and they would overrule your internal policy in any case.
We will now open dispute via Paypal and they will no doubt give you a chance to provide your side of the transaction with all considerations to your policies also.
