Problems: Hardware failure. Refund delay. Overseas customer service.
Details:
In 2015 I ordered an Inspiron 3847 desktop computer. The unit failed during initial boot-up and it had to be returned. Their customer service put me in contact with the 'returns' department and the computer was picked up and returned the next day. At the time, I was told that my money would be refunded in about 10 days. However, two months and two phone calls later, the money had still not been returned. The people in their customer service department overseas were next to useless and told me, at one point, that they were "having problems".
I ended up ordering a higher end computer and it was fine. However, it seems that when you have a problem, it is next to impossible to go right to the source to get the issue resolved quickly and efficiently.
