Telkom home option - unhappy with current option

Hi. I have a Telkom home option R599. I opted for this as at sales stage the consultant confirmed there would be no additional call usage charges. the package included unlimited calls to all mobile operator numbers including national numbers from different operators. my bills included usage charges since month1 . I queried recently and was informed that the package includes limited numbers hat will incur usage charges. I am unhappy and have been trying to contact the Cancellation call centres. I have been holding on two occasions for more than 10min. the website reflects technical issues. I found an escalation email and sent my query 20Mar2015 after a week of trying the call centre. I got an automated response from this mail but no one has attempted calling. I am quite frustrated and would like to change my option back to what it was before this change. regards
