Bad service

This morning I called the Samsung store at the Grove for assistance approximately around 9.10 am the lady that took my call was so rude,whilst I was speaking to her she dropped a call on me. When I called a few minutes later,calls were not answered.I tried again and a polite gentleman assisted. I was asked him if I could speak to the manager but to no avail. Can you please run a professional business and not employ people who do not care about clients. I was left very angry and disturbed by the unruly behaviour. I have a Samsung tablet,hardly 3 months old but it does not switch on That on it's own is disturbing and on top of that you are treated badly by staff.
