Worst service ever

Service at HIfi corporation is the worst, been trying to conclude a credit application I did. I have been on the phone holding for 3 hours trying to speak to Xoliswa in the accounts department. She was going to call me back after 10mins, it's been 26hours. Needless to say, I have still not received a call and their lines are "receiving a high number of calls". Ridiculous really.
