Horrible, horrible, horrible company.
They are not in the US. The use a use postal address and phone number but are a bunch of scammers from the phillipines that provide horrible horrible service, are argumentative, promise refunds and keep you waiting till you cannot get Visa to do a chargeback.
You need to baby sit them.
They are persistent in calling and texting you over and over and over to get your business, but will not provide any accountability for the horrible service they give you in return. You'll even get insulted.
Stay away from these crooks.
