I believe that MAAF customers receive their MAC around 4/5 days after requesting it.
Out of interest why up to 5 days?
My old ISP provided it to me on the spot when asked for it. If they can do it, surely you can do it too?
Plusnet customers have to wait that long, so MAAF customers can't be treated preferentially
In the Brightview days MAC codes were given out when you phoned up CS and asked for one.
Or is this where you're hoping the customer will change their mind by the 5th day?
The customer retentions team will offer you a deal they think you won't refuse
