Shocking service

The service is shocking, I have dealt with WCTV repairs in the past and compared to the service I received this time around I cant believe its the same establishment. I booked my item in on 15 Oct, paid an upfront assessment fee only to be told "no fault found" a week later. No feedback, I had to call for this, I went in to explain the fault and actually demonstrated the fault to the technician, called a week later and was told item is ready for collection, went in only to find out nothing has been done. Spoke to the technician 2 days later again I had to call, parts were ordered, a week later and a few calls as well, now Bianca advised me supplier is missing they cant get hold of them.... imagine! asked to speak to a manager not available other one is on lunch. How does a business even operate like this. I personally run a business and I would never in my life treat a customer like this, to date this is the worst service ever received from any company and the reception staff I'm not sure if they know that if it wasn't for a customer they would not have a job, my advise is find something you love doing, don't just be there for the salary otherwise your customers will disappear one by one.
