TP Customer Service Representative interview questions

Easy interview simple reading tasks to carry out, all automated. Got the job the next day completed onboarding tasks. No communication for weeks, I tried to contact the company got an email saying they were busy as they had hired 3000 people. I had a start date and emails saying I had to be available for training and delivery of the computer. I handed my notice in at my current job and got an email 2 weeks before the start date saying that my start date is cancelled and they will get back to me if and when the contract goes ahead! They stated that the offer was conditional but I have completed everything asked of me. Absolute shambles! I'm a single mother soon to be jobless. Do not go near them.
