When I picked up my racquet from a local chain sports store, the string job felt like it was at about 54 lbs, when I had specifically requested 59 lbs. The young stringer wasn't there, so I just took the racquet and thought I must be wrong, only to get it home and find it was much looser than a racquet I had strung at 59 two months ago. Well I went ahead and played with it anyway last night and was spraying balls out all over the place. I also requested two piece, and he did it one piece(which I wasn't really concerned about). Do I have any recourse with this store /guy? Or did I just learn my lesson about not going to generic chain sports stores for string jobs? BTW I supplied my own string for the job.
