It is missing a lot here.
# 1 – He contacted us by e-mail to request information about the server, port 10G, etc. before the purchase. It has been clearly stated to the customer that the port itself is 100% dedicated, but if it is based on the customer's usage scenario, it does not mean that it is physically possible to deploy the full 10G port. For example, anything that requires intensive research will generally limit reading speeds (I have not provided this exact example). It was also mentioned to the customer that performing speed tests to try to achieve a full 10G would also be difficult because there are not many test servers on the market with a 10G port completely unused (regardless of distance, peering, etc.). I can provide logs of these two pieces of information.
# 2 – We offer a very clear policy without refund. This is mentioned in the terms of service you accept, in all our emails prior to payment, etc. We offer 24×7 support via chat and tickets and will go as far as necessary to ensure that everything purchased is delivered as advertised. In this case, it was the case (the customer will say no, but it was 100%).
