Pathetic after sales service from Samsung

On the 4th of February I called the Samsung call centre for assistance with a faulty fridge. After being thrown from pillar to post and waiting for over 30mins, I was finally assisted and they logged my request. Two days later I got a call from a lady asking me about the service I got from the call centre. I shared my experience, which I deemed horrible, and then asked her to follow up on my request, because I had not been contacted by the technicians yet. Today is the 12th and I'm still waiting. So I decided to follow up and the consultant I spoke to could not tell me why they hadn't contacted me. I have since been promised they will call me tomorrow. This is really appalling for a company as big as Samsung. All the electronics in my house are Samsung and every time I've had a problem, the service I get is shocking. This is a service I am going to pay for, and I would expect much better service than this.
