Is ABS module damage related to improper caliper installation?

Thank you very much nissandude. I'm a novice when it comes to vehicle repair (currently in graduate school). I had to go back to this mechanic twice for brake work within one week and I'm highly suspicious that the issue was related but they vehemently denied it. This is from my receipt...
