Disappointing customer service

<p>I would like write a report on mtn. I entered the make your wish competition with mtn and after a few weeks got a call from then letting me know I had won a smartphone. They took down my identity number and asked me what's my full name and surname and which store is closest to me. I gave them all the details required from me. Ever since then I have had no communication from mtn. I contacted there facebook page and they always say they waiting feedback from the competition's team but up till today I have had no response from them. I am utterly disappointed with there service. Why do there call up there customers saying that they have won something but don't deliver on there promise. Please stop misleading customers</p>
