Worst customer service

We had a laptop that the screen was cracked so we ordered and payed for a new screen through partserve. When they got the screen we booked the unit in for repair with a promised date of 3 to 5 days. They then told me they had to access the unit when it was clear the screen was cracked so who knows what they were checking. 8 days later I am still waiting for the unit be be repaired after getting told to come and pick it up. This is the second time with such poor service.
