Scam alert

A total scam!! I ordered 1 item, was billed for 3. Five days later, no shipping number provided. I've communicated with the company via their email address, replies are AI generated. Make sure you read all the other 1 star reviews as they provide a lot more detail than I have. Avoid at all costs!!!!

WORK IN PROGRESS!!!!

Well the representative was very helpful. She sent me an E-mail right away. The only thing is, she didn't send a company name or address. So I guess I'll have to call back and get that information.

This company will rip you off there is no refund available. I ordered 1 and somehow they took the amount of money for 3 and they charged me 3x shipping fee when they all turned up in 1 package. There is no point contacting them because they just don't want to know. I'm now in the process to see what my bank can do to help. But please,just stay away from this company. There totally shit.

Need a link so customers don't do what I did which was to poceed to the other items no realizing my order was processed.
I thought those extra items were a freebie.
Please refund the money for the air pump. I already have one, does not work very good.
Refund for the traffic police device. This item is not allowed in some states.
Thank you,
