VODACOM! Pathetic service and useless call centers

It has been 2 years since we are trying to settle this account. I have called the call centre numerous time and they put me on hold time and time again for up to 20 mins to half an hour. Also, when I lost my job in 2016 i advised them that I could not pay the account. No one contacted me alternate arrangements. I now go to the store, a different store all the time to pay this account but they wont accept my payment as they say is handed over! Why cant I just pay this at the store and get it of my back? Do you guys not want your money? Is there any one in your call center interested in assisting? Im so sick and tired of the incompetence of the call centers! If i dont get any feed back from anyone i will go to consumer watch and every social media to get this resolved! Im sick and tired of it!
