Network lock

[Bobbyt9]

I have a Sony Xperia z5 that was on a pay monthly contract. On leaving O2 I found the phone was locked and I needed a code to unlock it. This was requested and arrived but unfortunately failed to unlock the phone. Today I was told because I tried the unlock code more than 3 times the phone is now locked and O2 nor Sony can help me unlock the phone but third party companies can. I don't like the idea of third party companies and I really do like my phone so what can I do. I have escalated the complaint but there apparently isn't a solution to unlock the phone via O2 or Sony

any ideas?

Who supplied the code?

O2 supplied the code to me but allegedly they received it from Sony

I have given up with the phone now as I need to get my business number back in operation, so have accepted the offer of a refurbished xa1 ultra as a replacement

All that's left to do now is sort out compensation, but I'm guessing that will go all the way to the ombudsman. Fingers crossed it wont

Let us know what happens and good luck.
