Hello Tivaria,
I understand price increases are disconcerting. Unfortunately, the cost of everything has gone up in recent times. I understand you still have some remaining months with the promotion your received.
Have you had a chance to view the detailed billing? You should be able to view those details via your My Account --> Billings & Payments --> View Bill. From there, you should be able to Save and/or Print a PDF copy of your bill. That PDF should include the details of any price changes.
You should note that since Fido switched from their old subsidised plans to their new Payment Program, I don't think plans are contractual anymore. If you have a contract, it applies to the device financing only. So I believe the monthly cost of that plan would be subject to change. That said, I believe your discount should still be applicable for the remaining months.
In which Province do you reside? I'm guessing the monthly cost of that plan increased to $60. With your promotional discount, you would be required to pay $50 plus taxes. Is it possible you live in a Province with 5% taxes?
If you would like to discuss the details of your situation, you would need to contact customer service. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers

Hi tivaria,
can you make me a follow-up? Problem resolved?
Waiting for your reply 
Have a nice day
Hi Tivaria!
I think there was a discount in your account for 6 months, or Fido updated is price. Sometime phone company upgrade his price each year. People working at fido are great person, you should contact them to see what is going on exactly and if there are some options that may suit you.
Here the Fido Customer Number (888) 481-3436
Have a nice day I'm with you
Hi @tivaria,
First thanks for your quick follow-up . I think your case is an isolated case. Normally every telecom company are subject to price upgrade. I'm an Fido user like you but if you got a 10$ discount on original price for 15 months you should have your discount left, but have you checked if the price is now upgraded from 60$ to 62.50- 10$discount = 52.50$? It's could be the case. If the discount of 10$ is still here, it's only a price upgrade. I know your deal was for 50$ per month and your opinion matters. Fido is a great company, and the service is great. I know your saying your not asking for a new deal. I think Fido is trustable and honor his engagements. The best way to have a clear idea about your billing issue and explaination is to chat with a Fido rep at Fido.ca, maybe he can adjust billing. I'm an user so i can't get in billing details so i tagged also some Fido forums mods in my reply, so i think your post will be answered by @FidoSaad , @FidoStephen or someone else at Fido.
I hope a solution will make you feel better, and make you smile
Have a nice day Keep your head up
