No exceptions for long time customers

I have been a customer of Mweb since the Big Black Box(1999). This month my residential estate signed up a fibre company to provide fibre for the whole estate. Unfortunately the supplier does support Mweb as an ISP and I am forced to cancel my ADSL service with Mweb, but I am keeping my Mailbox and Hosting services with them. On Monday the 12th of February, I gave notice of my service cancellation. I was then notified that a calendar month will be enforced and that my service will only be cancelled by the end of March. As their billing is in advance, this did not make sense to me and I responded to the notification with a request to kindly reconsider and make an exception for an almost 20 year long customer. They responded again and said that they will not make an exception and that they are enforcing their T&C's.

So much for long term loyalty, as it means absolutely nothing. Due to this, I will be cancelling ALL my services with them, and NEVER support them again, as I just got spat in the face for my brand loyalty.
