Recycled our number without warning or protocol

MTN decided to recycle my wife's business number without her knowing. Their policy states that they will do so in 90 days of inactivity. We activated (with monetary input) on Sep 8 and the number was recycled some time in October. It STILL isn't 90 days since activation.

Their responses include "It's an automated system" (Like I care) and "We will deactivate a number after 90 days" (I know, read my email properly please) and the latest one "Kindly note the number was recycled and given to a new user. Please visit the nearest MTN store to get a new MTN number."

And here we stand at a loss because we had to reprint all the signage that contained the old number. You made us lose money, MTN, and show absolutely no remorse.
