Faulty goods received

We purchased a phone from an Ackersman store less than 2 weeks ago. From day one the device was not working and the touch pad was faulty. It also did not charge properly. We had purchased it for an employee who took the phone back. They now tell her she must wait 1 month for the phone to be fixed?? This is in contradiction with the CPA and we would like an immediate full refund failing which we will take it up with the respective authorities.
