mtns incompatance

I had recently app**** for a contract cell phone with mtn online, i was concerned about the status of the application as i forgot to save the reffernce number, hence i went to the nearest mtn store for assistance. In store a consultant had told me my application was approved and i could collect the phone, i just needed R150 to buy the sim card, which i didnt have at that moment. As a result i went today and requested if i can check for a different cell phone but i was told there was a error on my profile restricting me from checking if i was able to get the phone or not, which the consultant had told me he will call me once he fixes the error. In doing so he opened 4 different applications which where rejected and due to the error it will not allow me to take more then a sim contract. It is unacceptable to provide false infomation to a customer then continue to open more then 4 applications which wheere not consented to which lead to me not being able to collect the item that i was told was approved. The online consultants were not much help with just informing me the error came from their department, which they fixed but the entire applications(inculding the approved one) being rejected compeletly. Sending me running around in store and over the phone with online and in store cunsultants. Mtn has completey wasted my time, money,petrol and have a complete disappointment.
