mondo mobile misleading people

On the first of June I got a call from Mondo mobile for an extra contract for R129 (Samsung galaxy grand neo plus) which I accepted, when the unit was delivered it was a pocket neo (05/06/15) I phoned Vodacom the same day and they told me that they will logged a complaint ,Saturday (06/06/15) I called again because the line was activated that day, they told me that they will follow up and get the recording from Mondo and so it went on. Yesterday I got a call from Mondo saying they cant help me because its out of the 14 day period Vodacom only send the complaint to them yesterday, the worst thing is that they already deducted an instalment and the other is due now again but I haven't been sorted out I don't want to cancel the contract I just want the unit I was promised or a copy of the recording I had with the sales person ,its almost a month and nothing was done by Mondo or Vodacom. Please people don't take anything over the phone from Mondo Mobile you will have a lot problems and your problems wont get sorted .
