DISGUSTING SERVICE!

I am so disgusted by the Samsung Care Store in Century City. Took my cellphone there on the 20th Oct and the lady who assisted me told me it will take 3 to 5 working days. Well it's now way more than 5 working days. I called numerous times without any luck. Emailed no response. Called again last week Wednesday and was told that I they waiting for parts and my phone will be ready the Friday or Saturday,but they will keep in touch. I called Tuesday the phone rang yet again. Called yesterday, Wednesday just my luck someone decided to pick up the call, the guy told me that he will look into it and call me back,I asked when he said by end of the day and I am still waiting for that so-called call. I called again later morning..my luck again after 3x calling. Someone picked up and told me she needs to speak to the engineer who goes by the name of Debbie and she will call me back end of the day and yet again I'm still waiting. The service is so so so bad as a customer I need to keep on calling..this is not ON. I'm so angry and I will not buy a Samsung phone again! I'm so disturbed by your service Samsung,that I will take this matter further!!!
