Appreciate the quick response and delivery of program with requested changes. But the program had too many bugs in the beginning it took a long time to fix all of them. Would have been better if the you had tested the program for bugs yourself and fixed them before delivering. Even though the first version was delivered very fast it took so long for me to test each feature and request fixes and then wait for updated version which I had to test again.
Testing and fixing bugs in a software program should be part of the your work.
