MTN MOMO

Last week friday we deposited R3000 into the MTN Momo account till today it hasn't reflected, tried calling the since friday but no luck in resolving this, spoke to Pamela, Nosi and a guy called Bathu if I'm not mistaken, I requested to speak to their manager Lwazi Mngoma in the morning and they said he's busy he will get back to me, nothing,I called around 13:00 I was told he's on lunch, I must try around 13:30, I called around 14:00 they told me he's busy he will get back to me, I'm really furious with this back and forth.
