CAR Magazine Non Delivery

I have been a subscriber to CAR magazine since the early eighties. In the last 18 months, their delivery service is shocking! As much as I appreciate postal delivery issues are the major cause, we, after many many emails, arranged a door to door delivery service. This worked well for 6 months and then stopped. Again, after numerous emails, nothing gets answered. When you phone, it gets answered and the person on the other side hangs up!. The only reason I continue is that CAR is such a good magazine. It is a pity that the delivery (and admin staff) can't keep the same standards. Not sure now who the right contact people are. It is no longer Magsathome and I believe it to be Highbury Media or Ramsay Media. Why encourage people to subscribe and pay up front when they can't keep there side or any deal. It is very frustrating!
