Cancelation harassment

Called vodacom contract cancelation and tried to cancel a contract for a for a data sim we are not using (my wifes backup phone) I explained to Nozipho why I want to cancel my contract and just want the number as a prepaid number . She from pillar to post trying to sell new devices to us and basically trying to force me to take a new contract instead of canceling. After repeating myself for nearly 5 minutes saying I just want to do a cancelation my wife took over the call and then had to for nearly 10 minutes repeat herself saying we don't want a new device we just want to cancel. My wife eventually called Nozipho out on her borderline harassment until she eventually stopped and in a very unfriendly tone gave us a reference number and ended the call... After years of being a loyal vodacom customer this level of treatment is pathetic I'm now convinced I want to cancel my other 4 contracts and completely leave vodacom
