Worst Service Ever

I ordered a laptop online they failed to deliver the first and cancelled my order without giving me any options. I had to reorder as I really needed a laptop for my studies. They delivered last week on the 26th a faulty Lenovo laptop and that is when my nightmares started. I called to report it on Monday and they said I must take it to the nearest Pick n Pay Hyper. I only got a chance to go there today. To my surprise their processes are so not aligned. Firstly, the staff at Pick n pay hyper at Centurion Lifestyle were not willing to help at all since I bought online they said they don't even know how long it will take for it to be repaired or exchanged. I was even taken to Shaun the HOD, who was not prepared to assist just like his staff. They even went as far as suggesting that I go to Hyper in Pretoria because that is where they have an online shop. I asked them to find out if they have it before I drive there, and it was not found on any system. I had to call online with my own phone and I was told I have to wait for 3 days to be contacted. I need a working laptop I can't wait that long hence I bought online.
