Yello Mobile

A call center agent called me telling me about this awesome deal yello mobile has on offer as curious a I was I opted in I was told the would deliver my phone within 10 working days I then got an SMS "Dear Valued Customer, your recent application with MTN has not met our criteria and we are therefore unable to proceed with your request" I then tried calling them and as soon as I follow the voice prompt and make my selection I get cut off the have debited my account and would like my moneys returned as I never received any product from them.
