Cardmember services failed to resolve my dispute closing the case reopening closing reopening closing. Finally I demanded claims and arbitration file# MX0801002032574 National arbitration forum Minnesota [protected]. The case involves microsoft software vista I bought at Target after purchasing the software for over 200.00 and putting it on my newly built system. The software stated it was a illegal build 6000 it was made in Puerto Rico shipped from canada. I checked with microsoft and the product key was valid now card member services refuses to give me back my money according the Visa rules and regulations stating if you have a problem with goods and services you pay the first 50.00 well because I paid 217.00 and accruing interests I should claim 250.00 and I have sent the 3 agreements to arbitrate with no response.
