Contract Query Cost Me Money

I tried to apply for a mobile deal online on 12 January and have since had to follow up on the application by phone call because the agent assigned to me was not calling back. When she did phone, she first argued that the package i had selected was an impossibility despite having selected a packaged deal online. Following that, she sent me to Transunion with the news that I was 2 and 6 months in arrears on some accounts and must phone Transunion to check which ones. Their report disputed this, and was charged at R80. Upon return to MTN, I was asked to mail the report to a Louraine, but again had to phone back twice to get further feedback. I was then told by a third agent today, that the reason for the decline was not arrears, but that I defaulted a clothing acc payment during a time when I was unemployed last year. I asked why I was sent to buy a credit report, only to have the reasons for my decline change once the report gave us an all-clear in the area mentioned, as now it appears it had been a futile errand. I was then told rather unremorsefully that a) agents used different services for ITC & b) I cannot log a complaint for an unnecessary credit check even if it cost me money
