missold customer sick of telkom services

I app**** for a contract online, i was called by a sales advisor of telkom. I app**** for a cellphone double deal contract and then the sales advisor offered me a deal for 11Gb of data per month for 24 months at R139.00 per month of which 10500mb will be daily data and 500mb night of which total 11gb. He told me its one of there june deals that his offering me now as a once off as it wont be avaliable again. I agreed to it i had such alot of miss information given to me by this sales advisor i now found after getting ky device on friday nd opening it on saturday that he placed me on the incorrect deal. He put me on a 500 md day nd 500mb night with 10gb telkom wifi that i can only use if i am in a telkom wifi area. I called the customer care line many times nd their systems is always off line nd they give me half information. I request to a manager to explain my complaint nd req uf the manager can keep me up to date with my complaint he told me once agaim the system is offline nd he can mot follow up with me i must call in if i heard nothing yet in 24/72 hours because they do not have a follow up process or i can call sales. The line made a beeping tone nd the call ended nd the manager never called me back or sent me a email or text explaining what happened why the call ended. Telkom staff can care less bout the customers even if they are missold. I have till friday to cancel my contract but i must wait till wednesday for feedback. I am sick by the serivces i recv from telkom nd very upset nd thinking of cancelling my contract if i get no feedback urgently. Not one person took responcebility regarding my complaint simce i spoke to the sales advisor as he gave me misinformation amd missold me from the word go. Hope this dont full on deaf ears like the staff that works for telkom.
