Vodacom Has Green Fever

Good day As u all know i have done a review last week, Well Vodacom was very prompt on fixing my one problem, totally ignoring my 2nd line problem, How ever, when they got the one line of mine working, i email back to them rejecting the fact that the job is complete, due to the fact that they use indoor LAN cable for outdoor use on a tower, this morning they clearly ignored my email, and closed the ticket, No that same line is down again, and as always no response from Vodacom
