Why was a order to put in to change my upload speed

[#1]

Hi Guys,
My first post on the community forums. I am on Fibre and yesterday morning I woke up to an email from plusnet support saying "The order we placed to change your upload speed has completed."
"Your upload speed is now "2Mbit/S"
I was prior to this getting upload speeds of 20Mbit/S  why would plusnet do this. I pay for fibreoptic broadband so expect to receive this and not a measly 2Mbbit/s  I have also note that my download speed seems to be slower now also.
No a happy bunny.

This change is due to a bug in Plusnet's systems. See thread Out of the blue email about upload speed being downgraded. I expect a modify order to correct the problem will be placed on Monday when the Digital Care Team staff are here again and see this topic.

Hi there,
Picked this up on another thread for you, the order will complete tomorrow morning. Sorry about that.
