Terrible service

<p>My contract was upgraded in August 2015 and in the past year I have had to have about 5 or 6 time I have actually lost count. I went to Samsung thinking they were they problem but they are not. Every two months I am having to get a new sim card. We phoned the call centre and explained the problem and they gave me a reference number, we waited 48 hours and they gave us another reference number. It seems like they do not know what they are doing. I got a sim card yesterday and we phoned last night and got told to wait 2 to 24 hours for a phone call and we didn't receive one then we phone again now and they say they have to esculate it again. Please sort your problems out. </p>
