Unable to speak to anyone at head office

<p>Enquiring about MTN erecting a mast in a game resesrve, made contact with Astrid (Muller?) who said she would revert. i have left several messages on the cell number she gave me to no avail. Try calling head office, where she works. Most times no-one answers the phone and if they do, still unable to connect me with ANYONE to help with my query.</p>
