Telkom being ***********

In around June i did an upgrade at Menlyn telkom store (Pretoria) and Edwin was assisting me, I specifically asked him to put me on top-up option, few days later when i call Telkom to inquire they said to me I'm not on top-up however they can change that for me i I cant remember the name of the consultant correctly but the date was around the 28 of June if I'm not mistaken. Moving right along this morning i bought airtime voucher recharge i couldn't load airtime i have been on the line since 8:00 this morning trying to sort this out i have been transferred from one consultant to another, the last one that i spoke to by the name of Noxolo from 9:00 this morning she then said to me they cant change my plan to top-up i have to pay for that however it was not stated anywhere on my contract and once again i have plead for them to put me on top-up. I dont understand how Telkom and its people works.
