Is there anyway I can get my money back or find the person who scammed me?

I got offered a iPhone 6 for £200 from a company in London and all I had to do was pay some money and I d have it in a week (today) and now everytime I ring up the number isn't found but the man gave me some bank details and a name so is there anything I can do

If it's a scam, the bank details and name are almost certainly going to be fake/someone else's.

I'd suggest you speak to the police. Certainly continuing to call the disconnected number is going to be no use to you at all.

If you could get your money back it wouldn't be a scam.

File a police report. This is considered Theft by Deception. Go to your local station with copies of all emails, a copy of the bank transfer, the receivers account details, etc
The fact you have bank details is a good sign as UK banks require loads of proof of identity before opening an account
Why did you think you could get an iPhone for £200 when the wholesale price to authorised retailers is £350? You had to know it was gong to be stolen, a Chinese knockoff or a scam at that price

Ever heard of the phrase "if it's too good to be true, it's probably a scam". Unfortunately, 200 pound is chump change, so neither the police nor the central bank of the UK will give a rats *** about your unfortunate mishap. Essentially, learn from this lesson and don't be taken again in the future.

Nothing you can do other than phone the police but with so little to go on it is unlikely you will get your money back. The moral of that one is that if it seems too good to be true then it is likely to be a scam
