How many times must one complain?

I wrote a report on Telkom about a week ago - and our problem has STILL not been fixed. Their Social Media team phoned me yesterday and promised to call me back and resolve our problem... Did I get a return phone call? No. We have been without internet (WHICH WE PAY FOR) for over a week now. I am a web designer and work from home - how much business must I lose before this problem is resolved.<br> <br> We have phoned the \support"line numerous times and each time we get the same response... and still... the problem persists. Yesterday we were promised that a technician would be out to check our line... did this happen? No.<br> <br> Its beyond ridiculous - until this matter is resolved I cannot work - Im losing money. How many times must I complain online before something is done?<br> <br> Our reference number for the fault we logged with you (LAST WEEK WEDNESDAY MORNING) is: 31CWK021215<br> <br> My patience is wearing thin... terrible service!"""
