MakeXYZ refuses to cancel my account and stop charging me $9/week for their “promotional service”, complete silence from their customer service. What can I do?

I’ve emailed them six times by now at two different emails, called them on an unlisted phone number my credit card company gave me, and… nothing.How is it possible a company can continually charge your credit card and refuse to stop? I’ve gotten charge backs 2 times now for all the damn weeks they have charged me, but they just don’t stop. Surely that can’t be good for their account?I’ve already messaged them on Twitter and Facebook. What else can I do that shows them I will not be screwed over easily?If you are considering using MakeXYZ.com for anything, do yourself a favor and use 3Dhubs instead. MakeXYZ is the Comcast of 3Dprinting services IMO http://ift.tt/29kHg78
