StackSocial advertised the promotion price for a product and the code on the Internet in many places. I purchased the product but applied the wrong code which they sent as well. So I did not manage to get the correct promotion price at the end. I made a reasonable and fair request to adjust the price to the promised discount. The voucher code was wrong. I sent the correct code as they advertised, or simply correct the price. The helpdesk refused to change the code. Helpdesk referred to the company policies. This is really terrible. What an awful experience! It is simply a scam.
