Disgusting service

I bought a computer from them in January and the service was wonderful up until I received the computer. The modem was not working so I took it to telkom, they said I had to go back to Livdigital which I did but they said they would come back to me. They didn't & I became frustrated and went back to Telkom who changed the sim card & it still didn't work. I contacted Livdigital & was promised a return telephone call or email. She came back to me with a long letter saying I needed to bring it in, what is the purpose of online shopping if they don't have backup service. Eventually after three weeks of back and forth of being pushed around from one person to the next they said they would send someone on the monday to collect the computer. They never did & I waited another week, phoned & emailed several times. They collected the computer & said they would return it in a three days but no surprise they never did. Eventually yesterday they returned the computer & while the driver was still here I tried to use it and surprise surprise it never worked. I am appalled by the uncaring and non nonchalant attitude they have its like they don't care. Nearly 4 months and no working computer
