Very Bad customer service

I took my handset to The CT smartcentre i explained the problem and they did a software update and said if it persisit I need to bering it in to be sent away for assesment. The issue still persisted and i took the hansdet back.On arrival there was nobody at the front desk and I saw a queue, stood in the line for about 15 min as there were only 2 consultants assisting the clients. When they were done with the 2 clients they called out numbers and the clients that came after me was next to be served .I told the consultant that I have been waiting 15 min already and now they helping clients that came after me. They said they cannot assist me as I did not have a number, asked where I got a number and they said at the front desk. Went to the front desk, again nobody there and I asked a staff member that walked pass the desk for assistance and was told I have to wait for the person assisting.Waitied and then was handed and handwritten number, so I had to wait again for about 30 min before I was attended too. I then discovered you have to pay an assesment fee as well.Very very poor customer service
