No emails for 4 days

Monday 4th May - I reported to TELKOM Call Centre that I was not receiving/able to send any emails. They were bouncing back to people sending to me. Also can not retrieve via their website. Got reference number<br> Tuesday 5th May - called Call Centre, no developments<br> Wednesday 6th May - called Call Centre twice, again repeating the whole story each time (one time the guy couldn't even find the reference of the initial call). Got another reference number to confirm issue was being escalated<br> Thursday 7th May - called Call Centre twice, both times they promised to get IT guys to prioritise, and to call me<br> <br> STILL not receiving/able to send emails. Am possibly missing business because clients can not even reach the automatic response on the webmail site - email just bounces back. Have wasted hours of my life hanging on for call centre and re-explaining in vain. TELKOM PLEASE HELP
