Bad communication and promises not being fulfilled

I was due for an upgrade, went into the store and was told they have stock of the S6 Edge. When I got to the front of the queue, they informed me that they dont (took me 1 hour). Then they needed to do a credit check, employee said within 3 days we will have the phone. Its a week later and there is nothing. <br> Customer care said it would take 20 hrs to be resolved after my phone call complaining. It has now been a day and they tell us it cant be resolved as that dept is not in today.<br> <br> This is pathetic service from Telkom. I am paying for a service and there is no support after the sale has been made
