Terrible service to new customers

I app**** for a new contract at mtn northgate with a staff member by the name of gift on saturday 18/04/2105. He submitted my appliction to the vetting department and said i should receive a message the next morning and if i dont recieve it by 10am i can come through to the store which i did but he had not received approval which was fine. Today morning Monday 20/04/2015 i receive a msg of approval at 08:43am, went to mtn northgate and Gift was off but was helped by another consultant who then tells me i need to wait for Gift to get back tomorrow because the system does not allow him to conclude the contract. Does mtn expect me to keep driving to their store because of the lack of communication and outdated systems. What will you guys do tomorrow, will you tell me to come back on Wednesday? I am not even a customer yet but receive this kind of service!
