A mere email takes more than 5 days to be sent!

I had a change of ownership done more than a week ago and requested numerous time from REJOICE that she sends me an email bearing neotel's letterhead that indeed the contract is in my company's name, i NEED this confirmation letter to succesfully register my business with a professional body, that was 5 days ago i was told 24-48 hours.<br> <br> Now 96 hours later i still haven't received this letter i'm beyond FRUSTRATION because i am about to lose a job contract because of this outstanding email from Neotel. Today (25-05-15) i spoke to Merriam and she told me that i need to wait another 24 - 48 hours for back office to send me the letter. I then requested to speak to her manager and she rudely hung up the phone on my ear!!!<br> <br> Is this what i've signed up for??? I DEMAND ASSISTANCE ASAP I'M AT MY WITS' END!!
