Extraordinary SLOW service and turnaround time

I first when to the Samsung Bryanston Branch at Ni***ay for cracked phone screen repairs only to be told to go to the Samsung Service Centre in Constantia Kloof myself. So I drive all the way there to wait a good 2 hours for service. I finally see a consultant who says that for my cracked screen to be fixed they have to replace the frame as well. I agree to this. She also mentions they will quote me for a new battery as mine was swollen, I again agree to this. A WHOLE WEEK later I get a phone call to confirm assessments have been done and I will get emailed a quote for a new battery - I again agreed. I call back a few times during the week to check on progress. Then end of the week I get email a quote, I IMMEDIATELY email back and accept. Thereafter I have been calling daily to check up on progress of fixing the most basic thing to happen to a phone - a cracked screen & replacing a battery that one can really purchase anywhere. I get told I have to wait 7 days for parts. Seriously? Shocking slow service as I previously took an S4 last year for repairing a cracked screen which was done in hours. I'm guessing your turnaround policy is 2 months. Shocking!
