Walmart Walmart's credit card readers damage chip cards Palm Desert CA

Be careful with Walmart credit/debit card readers.  Each time I try to use a credit or debit card with a chip on it at Walmart, the card reader hangs up on the chip and damages it.  I'm on my third copy of one of my credit cards and my second replacement of a debit card.  All were damaged by Walmart card readers in the stores. 

This has happened multiple times, forcing me to use cards without chips if I want to make a purchase.  I'm done with this company.  They can't seem to do ANYTHING completely correctly.  Their online order system for grocery pickup only lists some, not all, of the items that are sitting in the store.  The Windows program for pickup orders does not pass the substitution parameter to the store EVER. 

Adding something to an order I just placed required a phone call to tech support, as the change order link in the email did not work (it started a new order instead).  I've reported these issues over and over to area management.  They've promised coupons (which must be used in the store and which didn't work) and online discount codes, only one of which ever worked. 

This program is over a year old, but they haven't fixed ANYTHING.  And now, with chip cards, it's impossible to go inside to get the things that can't be ordered online for pickup.  What a waste of my time.  I'm a programmer, and I foolishly explained these problems, complained in writing a number of times, and...  I guess they just don't care enough about keeping customers or are too inept to actually do anything about customer feedback.  I can't believe they are still in business.
