Damaged S4 Screen

I brought in my phone in March 2014 at Samsung Bryanston for a screen repair, it was fixed without any issues as my phone qualified for 2 free screen repairs, today 10 April 2015 I brought it in for another screen repair and I am told that I have exceeded my repairs, I am explaining to the lady that I only brought my phone once for a screen repair, when she checks on the system she says that she picks up that I fixed my phone at some Boksburg store and some technologies store, I stay in Bryanston and also work in Bryasnton, I do not know any of the stores she is talking about as the only store I brought my phone to is this same Bryanston Head Quaters<br> <br> After several discussions the manager insisted that they check via my cell phone no, and now she picks up another repair but she cannot even find out where was the phone fixed and all that.<br> <br> I am very dissappointed due to the fact that Samsung seems to think that is my problem, I feel I am not getting the benefits I was suppose to get. I am a loyal Samsung customer, I just got a new note 4 and all my appliances at home are also Samsung.<br> <br> Please assist.
