Edgar’s incorrect online purchases

I am very disappointed with Edgar’s online shopping .. recently I have been receiving the incorrect products. 1 I purchased a jockey panty pack of five as shown on the website. But received a three pack. The invoice received with that package also started 5 pack. When I queried it the person from the call center said it was a mistake and they can’t do anything about it. It is underwear. 2. I purchased a pair of sandals for my daughter size 12. And size 8 arrived. The invoice also stated size 12. Now i have to make my way to Edgar’s store to exchange. This is becoming a really bother to do online shopping with Edgar’s.
