Unable to refund

For the last 10 months I have been trying to cancel my telkom contract. In February this year this has finally happened. Now for the last month I have been trying to get my refund. And every call to the callcentre says still in progress - being escalated - pending - call back in a few days. I do have a list of 10 service consultants that have been dealing with this matter and none has ever tried calling me to get this matter sorted - over 20hrs in hold to get this matter resolved. Do not like posting on complaints sites - as this will not make a difference in the business of Telkom - but only get an reaction to the people monitoring this sites to change the complaints rating from bad to bit better.
