customer service?

Sunday, went to Lowes.  Needed a dehumidifier.  Not a big thing, had the numbers, knew the exact type, but didn't know were they were located in Lowes.  When it comes to hardware stores I am complete idiot.  Wandered around for about 15 minutes until I found 2 Lowes employees.  I presented my note, and asked them were the dehumidifiers were?  Instead of looking at the note, they just pointed and said "over in Outdoor Power Equipment...".  thrilling...as I don't have a clue what an outdoor power equipment thing is, maybe a chainsaw?  I ended up in mowers, after trying chainsaws.  Still couldn't find the damn dehumidifiers.  15 minutes later, I was about to look online to see if I could find a map of the store I was in, when I rounded a corner and found another Lowes employee.  I asked her were the dehumidifiers were?  I showed her my note with the name, brand, and number on it.  She took me to them.  She informed "these are the only ones we carry during the summer..." then walked off, she seemed offended I had asked her anything at all.  Great, thanks.  I had to pull each humidifier out to see if it was the right one, then I had to find a flat bed cart, and drag/shove said humidifier onto it.  Can't lift heavy stuff right at this time.  Checked out (at least that was easy), then went outside.  I was informed that I could leave the humidifier and someone would help me load in my car.  When I returned with the car and waited a few minutes, no one came to help, finally I got out and drug the damn thing over to my car and shoved up into the front seat.  Now great my back hurt, I am pissed, hot, and have spent 40+ minutes in Lowes looking for one damn thing.

I have worked in the customer service industry, well, almost all my life since my teens.  How could Lowes be doing this better?

1. When someone presents you with a note with the serial number, name, and product on it.  You jump right on that bad boy!
2. You check your system, to see if you have it in stock
3. Take said customer to shelf, double check product to make sure customer is satisfied
4. Then ask customer if they need helping lifting and getting this item to their car

Problems 

• customer is wrong department...find someone in the right department to help customer before deserting them
• Never assume customer knows what your terminologies are "Outdoor Power Equipment" means shit to me.   You could be describing brain surgery for all I know.
• Never, ever point in the general direction of the product, always, always, walk the customer to it.  If you can't walk them to it, get someone who can.  

Will I be shopping at Lowes in the future?  Probably not.  There motto on their site is "never stop  improving."  Currently, their improvement is questionable and definitely failing in the customer service arena.   If it was one bad visit, I would chalk this one up to the cosmos, but repeatedly the service has been horrible over the last year.
