Over charged

I am new to forum.

So in February I contacted Loyalty department because I was planning on leaving Telus for Lightspeed internet. Reason I needed to lower my monthly bills and Lightspeed has some better prices then Telus.

After seeing if Telus was willing to match Lightspeed price, which rep did after I agreed to lock-in for 2 years.

The price I agreed to was $55 per/month for speed of 25 with unlimited usage, few days ago I received my March bill for $126 plus change... I was both shocked & PO’ed.

How to fix this ASAP... my anxiety issue is causing me a lack of sleep.

Thank you for any assistance.
