false information given about the contract

I app**** for cell c contract telephonic,the agents i speak with told me about the deals he was having and i was attracted with offer with following package J5 Phone,R100 Airtime,he also told i will receive 1Gbdata and so i was convinced to take the contract with the hope of receiving1Gb data,the phone was delivered last week to find out he **** about package of contract,i am real disappointed about this matter cause i i agreed to take this contract because i was i was going to receive data.I did call the customer service ref ***.,i requested them to provide me with the recording of my conversation with the sales agent whom i speak to about the contract,so that they can also listen on what we agreed,i am starting to be worried cause it seems they delaying the case which will result me paying for contract which i didn't signed for
