Axxes Internet Customer Service is Appalling

I recently placed an order with Axxes for fibre installation. Prior to placing the order, I received an email from their consultants advising that as of 1 April they would be charging installation fees.

After my order was placed, I received an invoice stating that I would be charged the installation costs. Called customer service to be advised that there's nothing that they would be able to do, as the email received contained a typo.

This was not an error on my end and I do not believe that ethically or morally that a customer has to pay for the mistakes of a company.
