MTN lost my phone

over a month ago i complained here on hellopeter regarding a phone i took in for repairs at an MTN shop, up to this day i still dispute the business ethics of MTN. So a lady by the name of Alice van der Merwe contacted me and to my surprise the repair centre now says I took my phone back, which is not true at all, then she later said she will find out from the repair centre, I HAVE SENT HER NUMEROUS EMAILS AND STILL NO RESPONSE... its been about 3 weeks since i last spoke to Alice van der Merwe, the phone was sent in for repairs in June....4 months now going on to the 5th month month....to top it all the repair centre made up some story about there being a physical damage to the phone, i still dispute that to this day, now all I want is my phone back, now I get told they gave me my phone back?? Wheres the release forms for that phone where i signed that I got the phone back?? This is unacceptable business practice and i am disgusted by the level of service I have received to this point
