I am in middle of a refund process. My return has been delivered for more than a week and there is still no update yet. 

The online customer service is horrible. I filed two service requests and both were closed without any explanation. I ended up with contacting a customer service representative and was told that it would take 10-15 business days to get my refund (I even don't know whether it's true or not).

I really can't believe it would take so long for a company like Dell to process a refund. Dell used to be a solid and trustful brand to me, but it's not any more. I really hope Dell can pay some attention on the customer experience.
