I purchased the audio video security pen. It did not come with correct instruction sheet. Took over a week to get some instructions thru email. Their email contact efficiency is not good. Too long between emails. I requested a refund for product due to direction sheet for operation of pen was not done properly or complete. No diagram for operating parts of product. After 5 weeks I still do not have refund for product. They have product. I sent back and returned thru mail. Their address and my return address were very clear on package. They won't tell me if they have received package. They have not refunded yet. Over $100 Canadian. They do not communicate thru email. I have sent 3 emails over 1 1/2 weeks and no response. I would suggest to myself that they have no intentions of refunding money paid for product but they are not going to tell me that. Their integrity is terrible. So how do I get my $100 Canadian funds back? Done thru credit card. They keep the returned product and the money and I get nothing. Their email communication is uncaring. I am George. I am in British Columbia Canada.
