Very unhappy about service provided by mtn

2015/03/07 tried to establish where unused airtime credit is going, and if it was deducted by mtn, phoned service centre the 1 consultant was very helpful, and he could go back in my history and said that there was 2 airtime transfers made from my airtime to a number which he could only supply me partially (not the full number), which is alarming becoz i cant transfer airtime gained on my top-up account to another mtn number, the call was dropped presume due to bad reception. so i called again the 2 consultant i was dealing with said that I should request my itomised billing reports and she did this for me. the call was also ended due to bad reception I would presume. So I tried again with 2 or 3 other consultants who said they cant access my history for airtime and could not help me so I asked to speak to one of the floor supervisors, but was informed that floor supervisor is busy and she will call me back. No one called back!<br> <br> secondly I phoned to find out if mtn could help with bad reception, but the lady said the fact that i could phone her from the area proves that i have reception, besides the fact that reception quality is very bad and only in spots. IS THIS MTN QUALITY????
