same thing, different store
Went to Lowe's in Trotwood[dayton]OH and found a 400 buck vanity and a 200 buck medicine cabinet. Medicine cabinet had slight flaw that would not show once installed . Clerk who worked in plumbing called manager named Angel who told him over cell phone we could have 10% off Clerk wrote ID # of cabinet and initialed unit. Trouble started when medicine cabinet was in wrong box. The box it was in was medinine cabinet of same manufacturer ,but the cabinet it described had a built in light bar and cost $100 moreThe box had the light bar illustrated on it as well. It was obvious that the cabinet inside the box had no such light bar. So,we had correct number from clerk and wrong number on box. Angel then shows up at cash register and takes the cabinet back to check things out. All he had to do was compare this cabinet to the displayed model to confirm that clerk's ID number was correct. He came back with a new cabinet identical to the damaged one and NO DISCOUNT. [he did this while I was in the restroom ,because I had to wait so long]
To make life easier for the checkout, I had already paid for the cabinet base and some other stuff that totaled $500. Walking away was not an option. Who wants to be stuck with a $500 gift card to a chicken crap outfit like this? Every person in the store heard me call angel's name. After waiting for twenty minutes the last time,my polite phase was over. I quickly apologized to the cashier that she had to stand there and witness this, but also told her that I needed to go outside and jog this off before I did something really stupid. I told her that if that idiot Angel and her had two options--either give me the discount ,or all my money back--cash or check and no gift card as I would never come to this store again. After all,had I not caught their mistake,I would have been overcharged $100 for the cabinet
After I came back from my run, she had everything in order,and I got my discount. She said that once a customer became as upset as I was ,that she was allowed to do what it took to get that customer's issue resolved. [in other words ,company policy to get me out of the store] Had she done this before I became upset ,it could cost her her job. She also said that she had no doubt that I was not trying to defraud the store. I again apologized to her that she had to see the brunt of my frustration because of the mistakes of others.
I guess it ''paid ''to lose my temper, but the stress I went through was not worth the 20 bucks. Maybe I will grow up someday,but don't hold your breath

The next time I will not pay for a partial order,and politely inform the merchant that I will go run an errand,and if they cannot resolve my problem by the time I return , I will not purchase the other items in the cart.
