So MTN is entirely inept, have taken it a step up to see what can be done, fished around for some more emails, Bridget Bhengu and Jacqui O'sullivan which I need to check, after having checked how their emails is formulated from name and surname. There is a couple of permutations I need to test, which can be done all in one email.
I wonder if I should push it that far ? tweeted to jacqui o'sullivan, and emailed bridget, want to see what happens in that regard first, before I start testing email addresses.
Next on the list, rob shuter and godfrey motsa, I figured out by looking at their email addresses from what I have seen surname is separated by . for example rob.shuter or godfrey.motsa some times there is an under score as well, capital letters I don't think makes a difference, here. (Found the CEO's email address

)
They likely have group email addresses as well like supportteam or support.team as well.I need to check what the mail server does with an invalid email, it will likely flag the sending email address as spam eventually so will need to setup a disposable email address or two to test it out.
I guess it's a lot of effort, but have nothing better to do today then annoy, conquer and spread evil today. Emailed the CEO.
So let the games begin.
