Very unhappy

I have app**** for a contract at Vodacom 4 U in East rand mall and only received feedback 2 weeks later just to say i need to pay R9000 deposit before i can get the contract. This is unbelievable. This is my first cellphone contract and i get this. I have to call everyday to follow up and each time i leave a message no one gets back to me. I am very upset about this. I was told that i can not afford the contract but i need to put down R9000 ***! This does not make any sense.
