Due to a "technical issue" we unfortunately did not receive your email

Why does the support constantly claim that they didn't receive the email due to technical issue? Every single time.

Fun fact: I have it in writing (from someone actually capable at support) that there was no technical issue and that all of my emails have arrived. He even quoted from the oldest one.

Another fun fact: The usually panic when I tell them about the proof. Sometimes they hand out credit like candy, other times they simply quit the chat without a word.

So, Virgin Media, why does your support lie? Yes, it's a lie (assuming that it's not incompetency). It's basically free evidence for arbitration.
