worse service ever experienced

i just cancelled my telkom contract new installation that i app**** for on the 12th of january. till today i have no line installed. they said it was a cable fault. everytime i call in they say its been escalated to cabling. the last time i called was 2 weeks ago and the cabling manager says give him a week and it will be done. its now gone 2 weeks and still nothing has been done after me calling in. its sad you get such pathetic service from such a big company its clear they are not worried about little customers and more. this will change 1 day when there is going to be a big competition company for them and they start losing customers, they will then regret giving this service.
