You will need to show these to the debt collection company.

That’s not really an answer though is it? 
The fact is, I cannot connect to a network because of a false claim. 
 

I have phoned o2 and one agent says there is nothing wrong with my contract, another agent said that I’ve never paid o2, the o2 store person told me to take another contract out. 
 

also, debt collection services are not interested in past payments, they have purchased a debt, albeit one o2 invented and they will want the whole sum because according to o2, “I have never made a payment”. 

I received a letter of termination from o2 claiming I had not paid them for over 12 months (proof that this is not the case has already been sent to o2 to either re-establish the contract or to terminate without further costs), however, since the termination, o2 have sent me a second new contract, which was not asked for and are now billing me a further €50 per month. 

1. What on Earth are you guys doing?
2. With this being o2’s error, will my credit score be affected?
3. With this being o2’s error, who’s best to speak to via EMAIL in order for me to seek compensation because of damages occurred because since having my contract terminated, I have had to gain network elsewhere and have to pay two network bills. 
4. I do not want to hear about any Inkasso conversations, I have already got a lawyer involved and according to the lawyer, an Inkasso letter is irrelevant until o2 respond with an outcome because this is 100% o2’s fault. :) 

Thank you

Hello @JS-87, thank you very much for writing to us here.

According to the letter, the demands already have been submitted. Please contact the department specified in the letter.

I'm sorry I can't tell you anything else here.

Kind regards, Ines.

If you have already contacted a lawyer, let them deal with this for you. That’s what you are paying them for! If the lawyer believes it is “100% o2’s fault” then they should be in contact with o2 to seek a resolution. A forum is not the correct place for this, and in any case once a lawyer is involved customer services cannot help you and communication needs to go between the lawyer and o2’s legal department.
