This company sales faulty equipment This company sales faulty equipment. I ordered a amp for my son for Christmas and it didn't work. We contacted customer support and got the run around. We didn't ask for a refund we asked for a replacement and was told that we have to send it to the company that made the amp. In other words they don't care about customer satisfaction it's not their problem.

Agree with the rest, they don't care about customers! Man, I'm glad I started off light, I planned on purchasing 90% of my system through them. That's not going to happen now. I purcahsed 38 sqft of the 3 in 1 240 mil deadner sheets and 19 of the 23 sheets have the adheasive missing from the 1/8" to 1/2" from the end. This must be cut off and can't be used. I contacted support, sent pictures, they assured me that they have sold "10's of thousands of sheets of them" and this is the first time they are hearing of this. Yeah.. right. So, I go back and forth through their ticket system and was told they were going to send out replacements on Jan 25th, 2023. I asked for an update on Feb 17th and on the 20th, they are asking if I still have the bad sheets. Which, of course I do, I stopped the build till this could get fixed. It appears on the 25th, they were jus trying to get me to go away. It appears they have no intention of replacing the bad sheets. Their communication is the worst, I'll not be purchasing anything from D4S again.

Trash Customer Service Purchased a couple of 12s from them, both were damaged. Made me pay shipping to get them fixed, and also made me pay the restocking fee even though I reached out the same day I received them. Customer service sucks, and if you receive a damaged item, it’s not their problem, and don’t expect to get your money back.

Bad customer service.One star for great products but… One star for great products but terrible customer service. Canceled an order took an act of God to get a refund.

Find another place if you want customer service Placed a order on Sept 20th UPS label marked shipped.I haven't received and UPS says they haven't received the items. When emailing either no response or the ones they answer is no answer. Customer service is the worst I've dealt with in a company and I've ordered alot of stuff from other places with no issues. The person that helped me seemed more suited with a coloring book and crayons than customer service. First and last time ordering from them.
