Shipping label to return device takes days to receive??

Hello, 

I'm getting frustrated with Telus as a simple email apparently takes days to receive. 

I have an old phone that needs to be returned under their bring it back plan. I went to one of their physical store and was told that they can't help me because I ordered my new phone online. The person "sent" me the email with the shipping label to help but I haven't received any email with attached shipping label. She told me that I should've received the shipping label already when my order was processed. None was sent to me. 

 I called *611 two times. Both times the agent "sent" the shipping label emails to two different emails of mine. But still no telus shipping label was found in any of my emails in both circumstances even though they wait for me receive it. The second agent I talked to said he physically can see the electronic shipping label but gave me a reason that due to black Friday coming up, telus has lots of orders and processing is taking some time for the shipping labels to get sent. He assured me that within 24 hours I will get the shipping label. I told him straight up that I don't believe him because I was told the same during my first call. 

Now my concern is in this day and age, emails do not take days to be received. Under telus' bring it back plan, users have 30 days to return their old device upon receiving their new phone. I feel that I've been getting the run around and eventually will get charged for not returning my old phone. My phone is packaged and ready to go. All that is missing is this mysterious, hard to get shipping label. I feel that I'm going to call telus support again in the next few days for the same issue. 

How long does it take to receive shipping labels to return phone? Is there another way to further escalate this issue, just to get shipping labels, because the phone agents are not of help. All they say is to wait. I'm afraid that I keep on waiting but eventually get charged for keeping the phone.
