H-E-B complaint: Cashier Rude

Just before checking out, I handed the cashier Victoria in lane 13 my coupon for two Kraft shred Mild Cheese for $5.00 and I accidently tore my coupon. The cashier said she would tape it and when it came time to scan the coupon at the end of my $181.79 purchase worth of groceries, Victoria said she couldn’t use the coupon very rudly said because it wouldn’t scan. Victoria kept insisting she couldn’t use the coupon. I asked her if she could key the code at the botton of the coupon, no. Then I asked if the girl that was packing my groceries, if she could get another coupon for me, well let me just say I was not very happy with your customer service from either one. The packer did get another coupon, I said thank you so much, no response. On the last note, They need to learn to pack groceries. Everything was just threw in bags and my bread made into pancakes. I don’t know how your customer service reps. were trained, but I am a Senior Citizen and didn’t need to be treated rudely. How would you want your mother or grandmother treated?
