    "Best Buy has the absolute worst customer I have ever encountered. The mere fact that you cannot call the store where you purchased your item, is outrageous. We purchased what was recommended, and it doesn't work. Can we call and speak with ANYONE state side, nope. Worst, buyer beware!!!"

    "Run, don't walk, AWAY from the service center at this location. I'm stunned at how little they knew about fixing a keyboard on a Dell laptop. \n\nIt took them a week to misdiagnose the problem. Then I took it back to them again and they decided it would take another week to totally replace to keyboard. \n\nNot wanting to wait another week, I went to Geek Squad. They looked at the computer, typed in a solution to fix an apparently "well known" glitch in Windows and solved my keyboard issues. Took two minutes and they didn't even charge me. GEEK SQUAD ROCKS!!!"

    "I have been a loyal Walmart customer at the Lewis Center location (store #2725) for the past 25 years, until recently. Recently, my delivery orders have frequently been incorrect or missing items. My last order, on October 4, 2025, included major items that were missing yet I was still charged. When I contacted the corporate office, I received a refund of $35.35, which included a $15 promotional code (XXXXX_____) to use on my next purchase, expiring January 2, 2026.\n\nToday, Friday, November 21, 2025, I visited Walmart for the first time in over a month to buy a few items and to save time versus driving to Kroger in Delaware, Ohio. \n\nTo my surprise at checkout, I asked the cashier to apply the $15 promo, but I was told I could not because I no longer have an active Walmart membership/account (no active username, etc.). \n\nFrustrated, I left all my purchases on the conveyor and walked out. \n\nI then called the local store at 740-657-1341 starting at 7:19 a.m. and continuing until 9:39 a.m. EST, but I have yet to reach a Walmart employee. \n\nI've called the toll free number, nothing. Email corporate office , nothing \n\nNo one willing to be accountable or responsible to explain to me how or why this happened \nVery sad that large market stores take little notice to the consumer \n\nIt's not a personal issue; its principle."
