Because my Dell adapter started to fray at the end that goes into the laptop (it's likely a design flaw), I contacted Dell Sales via online chat. The salesperson matched me up with a replacement adapter, I provided my credit card number to pay, and then it occurred to me that the fraying adapter, which I bought in May 2018, might be under warranty. The salesperson said, yes, it was, and advised me to contact Dell Customer Care (rest assured they DON'T care!) so the amount of about $55 would be credited to my account. I had to make about five calls PLUS literally, not exaggerating, 12 emails, and they still refused to give me a credit for my payment. Their only advice: Send the new one back, they will then give me the credit, and then I need to go ahead and buy the same item! This is utterly illogical. Normally, a reasonable business that really cares about its customers might request I return the faulty item that's under warranty, and they would then issue a credit. But I wouldn't be expected to send the NEW one back. Another thing: I usually have no problem dealing with people who have accents; actually, it's kind of interesting to hear how people from India, the Philippines, etc. speak. I have a strong NY accent myself! But the Dell guys have such strong accents I could hardly understand a word they were saying. I offered a simple, reasonable resolution, but they have refused to cooperate. Dell is being ridiculous and wasting my time and theirs. I just initiated a dispute through my credit card.
