Bad Service when fixing my notebook

I have handed a notebook to be fixed. First, it had to be collected by them and it was not done on my premises. Disappointing! They needed to replace a part so they needed to order it. They said that it would take 3 - 5 days for the part to arrive to them. It took 5 days, not 3. In between there were public holidays so it took way longer in calendar terms. Then they fixed the notebook and promised delivery the next day. Almost a week later and I am still waiting. Really disappointing and completely unprofessional and unacceptable. Don't use Teljoy!!
