Worst Service Ever

I had this problem over a year now, simple thing but MTN can't even reconcile it. There was a ********** contract that was opened on my name. The contract to be approved you need the following copy of ID, latest bank statement & proof of address. So what happened on my issue is that I lost my ID and to my surprise MTN was calling me saying that I have open an contract with them. MTN need to check all above to see if it matches my details on my ID number surely transunion has the info. I have being sending documents and nothing gets done. MTN need to check the employee that was processing that contract to see the documents if it's attached and it correspond. Why making simple think difficult.
