Complaint Review: Walmart

I have had several issues with Walmart.com orders this month alone, with the latest being that on 06/26/2017 I ordered Diet Pepsi and Diet rootbeer  ( total of 9 sodas in all) this order was for some unknown reason shipped as 3 different orders from 2 different centers  But Walmart.com sent me Iced Tea instead with 2 of the orders arriving on 06/29/ ( both orders contained Iced tea) I contacted them and they told me they would send out the correct items, but once again I RECEIVED Iced Tea. Again I called and stated I once again received the Iced tea and I was connected to Corporate (?) and was assured that the correct items would be sent out and lo and behold the replacement items were ICED TEA and not the soda I ordered.  once again I called and was told that I would receive the replacements on or about 07/03/ 2017, to which I stated that it would be too late for my needs. I was informed that I would receive a refund for the sodas, by Friday 07/07/2017.  today is 07/08/2017  On t07/06/2017 I received a refund for 1(one) soda only
