Walmart Canada Order ************** - Toronto*Billing Overcharge******@***.com*George Rothman**When I placed this order, I used code CANADA** and received e-voucher CABDSGC*Z* for $** off this order. When I submitted the order and applied the e-voucher, $** discount was accepted and deducted from the total to be charged to my credit card.**The total for the final order after it was delivered shows $** extra, with the $** discount cancelled for some reason! My credit card has now been charged $**.** (**.****.**), instead of $**.**. One of Walmart's reps informed me that the $** discount was reversed because I added one item to my order (for $*.**) the day before delivery. My account and the order confirmation email indicated that I could edit my order up to ** p.m. the day before delivery, which I did for one small item only. Cancelling any discount for adding an item does not show anywhere on Walmart's website or in emails advising me about the deadline to edit or the email confirmation of the additional item.**Why was my $** discount cancelled, in spite of the valid e-voucher? If due to a minor change before the deadline, without notification to me, that would be unfair, deceptive, unreasonable, illogical, unethical and illegal!!**I want the $** discount credited now to my credit card on file. Please review and confirm promptly**Thank you.*George Rothman*Tel. ***-***-****
