Bad service , false information

on the 9 October 17 i received a call from Kevin Corban ( Telkom agent) as i was due for an upgrade , everything went well , i asked him if what he was offering was a top up deal and he said yes and again to wards the end of the call i asked him if i would be able to go buy airtime and load it to my phone AGAIN he said YES . to my surprise i get a sms with the bill of R668.65, when i called the call centre and spoke to Kgomotso who told me that i was not on top up and that my monthly limit was increase to R500 and i never agreed to all that . i told her this is not what we agreed with Kevin . i was told the is nothing she can do to help , i must go to the store to fix this and because the contract is new i need to wait for at least 3 months to migrate to top up . i kept telling her that is was not my fault so why should i go to the store but the was nothing she can do . i dont have a telkom store near me and even if i did i feel why should i be the one running around , when from the beginning i was very clear what i wanted . im very disappointed with Telkom . now i have to take time off my work and find a store not forgetting that i must still wait for 3 months for this migration to take place . not happy at all .
