Hi
my controller battery will not charge
I did research online and a lot of people are having this issue
DJI
Alright Rich. Let's do something about this.
May I know the model of your drone Rich?
Me
Phantom 4
DJI
Alright Rich. What happened before you experienced this issue?
Me
I was out of town for a while and when i got back the battery was dead and won't charge. I have used this product maybe 6 or 7 times in as many months
it charges the drone batteries and it works when plugged in
thebattery just won't charge
i can fly the drone with the rc as long as i leave it plugged in
DJI
Did you charge it for 2-3hrs Rich?
Me
i charged it for several hours
no change
DJI
Alright Rich.
You can charge the battery but not the remote control, am I right Rich?
Me
yes
both batteries charge fine, but not the remote
DJI
Did you try to charge it in different power outlet Rich?
Me
yes, 2 different houses, in fact
DJI
I apologize but your remote control have some hardware glitch right now and needs for some repair.
Me
ok. no way for me to replace the battery myself?
DJI
The battery of the remote control Rich?
Me
yes
DJI
There's no way. It should be send for a repair.
When did you received your unit Rich?
Me
end of last year. oct i think. I purchased from best buy
DJI
Alright Rich. I suggest for you to buy a new remote control.
Me
buy? it is under warranty I spent $1300+ for something i have used 7 times
why would i do that exactly? it is less than a year old
DJI
Our remote control's warranty is for 6 months only Rich.
Me
this is a lot of bs
DJI
I'm sorry Rich.
Me
Its still in warranty. It will be a cold day in hell when your company ever gets another dollar out of me. i write reviews for google. see who it costs more.. me or you
DJI
Where are you located Rich?
Me
everyone is having the same issue with this crappy controller no wonder you sneaked in a lower warranty
DJI
I suggest to send it for a repair Rich.
Me
i will be filing a complaint with Best Buy while I am at it. Its still in warranty period,
DJI
I'm sorry for the confusion.
Me
i want a case number
Me
and your operator number
Me
and your supervisors operator number
DJI
I apologize Rich. It's still in warranty period and you can send it for a repair to us. The technician will do some assessment in regards with this issue.
Me
i would like an a replacement in advance
then there will be no confusion about whether i get charged or not
DJI
Alright Rich. I'll make a case for you.
I'll just need some information from you:
1. Complete Name
2. Complete Address
3. Email Address
4. Contact Number
5. Date of Purchase
6. Date of reported incident
7. Model of Drone
8. Do you have DJI Care/ DJI Care Refresh? (Yes or No)
Me
I need your operator number
DJI
I apologize Rich but I don't have resources for that option.
Me
I need the name of your supervisor
DJI
What I have here is a phone number +1 (818) 235 0789. I'm sorry but this is the only thing I can give now.
This is what you guys are in for. Maybe try calling instead?
The bottom line is that DJI has to be well aware of the issues people are having by now and their support is pretty lacking, in my opinion.
Did you happen to notice he didn't even ask me about firmware levels or the likes?
If you have one of these actually under warranty, get it in fast. They seem to be depending on the fact that most people buy these expensive toys and do not use them very often. They certainly are not claiming ownership of this well know problem they unleashed on us.
Just my opinion, but I would be reluctant to buy anything else from them. The Phantom features are great, but a product is only as good as the company backing it.
At this point, they have not given me any reason to have confidence in them.
