Clubcard points

Clicks is being very shady they have teamed up with engen for clubcard points however your points are not loaded I have over 30000 points from filling fuel that was and has not been loaded and when contacting them you are told to email them the slips so they can investigate when you try that you get an email saying your mail could not be delivered because they emails are full. Why partner up and promise something if you are not going to keep up to it. They are behaving like *****s.
