On my bill I noticed there is a message saying they will increase my bill by $5 a month in March. I signed up to the BYOD Promo Canada 75 15GB back in 2019. They changed my plan to few months ago to BYOD Promo Canada 80 15GB but kept on giving me a $5 discount but now they are raising the price by $5. I did not see anything in the plan details that the Promo price had an expiration. Can they do this?
