No Help

I am disappointed in the continuous lack of customer service in regards to my subscription for the Delorean car. I have been a subscriber for more than a year and my complaints are endless as I have to phone every month. Every month, 4 issues are to be sent to me. For example, last month I got 3 copies of issue 57... this month, totally skipped. This month, only got 2 issues (# 63 and 64)... Every time I phone, it is a warehousing problem and they will be escalating my query. Well, I have had a complaint every month since the day I subscribed. It is so frustrating. :-( The team leaders only spin stories to keep me temporarily happy. Rose says she will follow up with me... only to be avoiding my calls now. This time, I am passed over to a Silo. What do I do? The only reason I keep up with it is for my husband who had a stroke and it is a hobby to keep his mind active as he was a mechanic before. Now, my question is, what can I do to assist them to ensure that I get my copies every correctly?
