Bad Bad Service NO FEEDBACK

I wrote a report on the 18 December 2015 complaining about allocating my payment which is an incident of 07 November 2015 and they responded that they will get back to me within 24 hours but till today I'm still waiting and no one has contacted me like they promised to so my problem has not been resolved. I'm now tired of calling them because I keep getting different people everyday and I am tired of explaining my story over and over with no help from anyone. This is really a bad service in-fact it's worse than bad that I don't even know what to call it. Please if they don't want to help me they must just say so, so that I can stop wasting my effort, time and money spent on airtime because their lines are not a toll free.
