Disappointed

I am extremely unhappy with the services I received from Mobi Warehouse, I had ordered a July special of 2x Samsung Galaxy Core with Cell C, Once I had put through my application and it was approved, they had called me advising they do not have the color we had requested, they also advised that they are having problems with getting the simcards from their provider. I then bought my own simcards and sent them the details. I had called to follow up on the activation of these simcards and I was told that they were activating them as we speak and it would reflect on our side immediately, which this did not happen. I waited the entire weekend for the airtime which never came. Today I called and was told that it will be done today and I would need to wait an extra 24hrs. They are only offering to give each phone an extra R50 for the inconvenience yet I feel this is not the way you treat your customers.
