I am being harassed by telkom telemarkers using this cape town number *** They call everyday around 8am and 3pm on both my numbers to try and offer me a new contract. I spoke to some chick few days ago and told her am not interested as m paying for a ********** acc and don't have the intention with renewing any contract with telkom however these *****s still harass me.am aware it's telkom as both my numbers are listed in my contract and the chick does say she's calling on behalf of telkom . They call on both phones. AM REALLY GATVOL WITH BEING HARASSED BY THIS COMPANY !!!!! If this doesn't stop I will report to the consumer ombudsman as I don't even remember signing up to marketing consent .not sure why am I being harassed !!!!!. I DO NOT WANT TO RENEW ANY CONTRSCT WITH YOU , YOUR SALES PEOPLE ARE ****** and you always protect them STOP CALLING ME!!!!!!
