i'm really sorry to hear you're going through this, it's frustrating when you can't get help from the support team. i've had similar issues with other exchanges in the past and one thing that often helped was sending them a detailed timeline of events, including emails and transactions. it might be helpful to compile a list of all the deposits and withdrawals you've made, along with the dates and amounts, and see if that triggers a response from shuffle. also, have you considered reaching out to your local consumer protection agency in canada? they might be able to help mediate the situation and get your account back in order.
