They are fraud, please dont waste your precious time calling them. I have got the same issue. Have been chasing them for past 4-5 month. Though my phone is under warranty but dont come under screen replacement. I contacted t-care, they asked me to pick the phone at your doorstep, I was happy the kind of service they have but even after 10 days nobody came nor they replied. I requested each day but they really don't bothered. I would say that T phone is great phone having pathetic service.
