NOT PICKING UP THEIR PHONES

I took my Device into Samsung Repairs in Canal Walk and I was advised it will take _+10 working days. I was quite aware how long it will take for me to get feedback and indeed on the 10th day which was yesterday the 10/02/2014 my sister recieved a call from them and she advised them I was at work if they could call me the following day. No call was recieved which I was still OKAY with that. <br> For the past three hours, I have been trying to get hold of them on *** - *** - *** with NO luck.The first number rings none stop and the last two I engaged.Call customer care and one lady give me another number and same thing happened,called again and I was transfered with ***.<br> What it is I need to do to follow up on my repairs??Yes they mighy be busy but for full three hours,that shocking customer service if I must add my two cents worth.<br> This is very annoying and irritational!!!
