Have spent 3.5 hours trying to cancel a webstore order

Hi. I placed an order for a phone + line 2 days ago but realized I placed a wrong order and I don’t need it anymore. However, I am having a really hard time trying to cancel it.

I must have spent more than 3 hours calling Telus and just waiting to be connected to webstore team before getting disconnected eventually. 

I am a loyal existing customer with 5 different lines with Telus, but I am so disappointed with the customer service that I am having second thoughts about getting any additional service or continuing my current services as is. 

can someone please guide me if there’s a simpler way to cancel a webstore order? Thank you so much!
