S6 Edge Mobile Data Faulty

I got my Samsung S6 Edge on the 23rd of May 2015. Since I have had it I have had intermittent issues with he mobile data. It shows that there is connectivity (3G) while browsing but will then just stop loading. It does the same with applications, i cannot log into my banking app at all because the connection is lost the minute i open it. I cant use the tethering on the phone as the connectivity stops working as soon as a device is connected. <br> <br> I have gone as far as doing a factory reset on the phone but still nothing. <br> <br> I called Samsung and they say I need to take it in to a service centre, who cannot give me a loan phone, or tell me how long it is going to take, or what the issue is. The Internet is full of complaints about the same thing, world wide, yet the call centre tells me they are unaware of this issue. <br> <br> What i need is a new phone, and a phone that works. I am a die hard Samsung fan and have had every model of the galaxy series. I am feeling very disappointed in Samsung about this due to them not helping me.
