I have been trying for 4 months to get a refund from Shopify.com for an order I placed for the HD MIRROR CAM from an add in FB . They made a withdrawal on my bank account on 08/21/2017 for $159.80. I have sent several emails and made several phone calls, sent them screen shots of the order confirmation and they keep telling me they have no record of my order or emails. ..I told them I want either the product I ordered or a refund to no avail , I need help. What can I do? I am on SS , I'm old and I cannot afford to be ripped off like this.
