What are my options?

I've had the 4S for around 16 days now and problems with the phone still persist, is there any way I will receive my money back or will they insist upon repairing it?

Their return policy is 14 days. What problems are you having? By default, you have a 1 year warranty.

Yeah, I was wondering if the staff would allow some lee-way and the problems are associated with the network, I'm not receiving texts/calls until days later and I am frequently unable to make calls due to the phone disabling the ability to do so (the call button does not respond), the network signal bar freezes too.

You might have a defective device.
Bring it in and they will replace it.
Also try a restore and setup as new to see if those bugs are software related to your backup file.
