I experienced a few mishaps … First the online app was not working correctly. When I explained this to staffing I was still able to get a discount (but not the same as the online discount) I was told that my battery would be tested once the technician got here. The technician told me that he only installed batteries. (No testing).Staffing put in the wrong address .Only a street number with no relevant house number.(this delayed my technician arrival). He had to call me for my address. The technician lacked knowledge on how to get my battery out of the casing. Luckily I had looked at Utube prior to his arrival and was able to explain how to remove the plastic covering .(covering that covered the floor board). Overall the technician was very pleasant and showed great patience for the things that were out of his control.
