walmart fraud, rip off time membership is due, extract more money sooner. aurora Colorado

2011 I joined sams club. This was in july.  2012 on a routine shopping trip they asked me if I wanted to pay for membership early. This was may 2012. Thinking this would be a good idea I agreed.  March 2013 I was shopping and offered a samsclub credit card for 40$ off that days purchase. I agrred to it.  the next time  I came in it was may, and my card did not work,  The help desk told me my membership was due.  Take a look at the time line for first years membership and 2 years later. I attempted to argue with idiots, who could not see how I was ripped off for 2 years time. and then found my computer info they had to be incorrect, however they would not resolve, nor locate someone with further knowledge. I have spent thousands of dollars over the years at sams and walmart.   I find it reprehensible that they are obviously ripping folks off. I came in with my original paperwork from 2011.  I guess I will take my business to target and costco.  They have the philosophy " the client is right, and if they are not I will make every attempt to rectify the problem'.
