wrong contract and misinformation given to me

I went to open a phone contract at Game Midrand where I was helped by lady who had a nametag that wasn't written her name hence I wrote checker no 111 as it states on the contract. she was in hurry as it was knock off time I asked to come back tomorrow as I could see she was in a hurry but she insisted on continuing with the opening of the contract. she them misinformed me when I asked when will be the 1st debit she said on 25th of July which wasn't the case as it went off in 2 times. had I knew this I wouldn't have taken the contract that because I knew I didn't not have funds and this affected my credit profile. <br> I was shocked when my simcard was blocked due to being over limit and that's when I found that I wasn't on top up contract and when I went query this today the lady gave attitude, was rude and accused me of wrong information that she claimed I knew which is not true because had I knew I wouldn't have opted for contract as I know my financial abilities. the manager wasn't helpful either as the was no solution on the matter at hand only solution on contract change in 3 months. I am so not happy with treatment I got from this lady.
