Once I've shopped for portable vacuum cleaner by sale. Price was acceptable, item was shipped quickly, delivered via postomate (automatic postal box machine) service that was very convenient, but parcel was squized and damaged. Btw item in damaged box was in perfect condition. So, I've tried to switch on vacuum, but it doesn't. I've tried to charge item (it was), but after charging it still doesn't work. I've opened dispute and BangGood support replied me to provide them some photos and video of not-working product. After I sent them asked media, next day they said, they sent me new one vacuum cleaner for free. Now I'm waiting for parcel =)
