There are several threads about shipments from China.
But the short answer is: if you haven't got it yet, file a Dispute and get a refund.
Here is my canned response about getting refunds. Not all of if will be exactly what you need.
You have 30 days after that 'last estimated date for arrival' to open a Dispute with eBay's Resolution Centre, which is at the bottom of this page.
The first suggestion is to Contact the Seller. Don’t get into a conversation.
Just ask “When was this sent? What service was used? What is the tracking number?”
Don’t get into a conversation. You want either a prompt refund OR a tracking number that shows the purchase is in Canada.
Do NOT accept a replacement. It won’t arrive.
Do NOT close the Dispute until you have the product or the refund.
If you have already attempted to Contact the Seller, skip that step, ask eBay to step in and Escalate to a Claim.
If the seller cannot prove Delivery (not shipping, delivery) you will be refunded.
If the 30 days have passed, go to your Paypal account.
You have 180 days from payment for this Dispute.
Find the transaction and copy the number.
The PP Resolution Centre is at the top of your PP account page under Tools
Same process basically, skip the Contact Seller and escalate to a Claim.
If the seller cannot prove Delivery (not shipping, delivery) you will be refunded.
In future, read the feedback.
Don't buy from sellers with less than 98% positive (99% for Asian sellers)
Read the negative feedback , including seller responses, for patterns like slow or no delivery, poor communication, low quality, counterfeits.
