Activ have probably bought your debt at a large discount from ptsb.
Normally they only negotiate when they get a handle on your circumstances.
They on request, may send you an income and expenditure form. From that they can judge are you likely to be able to afford %%$$% euros or are you financially banjaxed.
Eg. If you earn 5,000 a month and have no debts , they want 100%.
Eg. If you earn 2,000 a month and have 3 kids and 1,200 mortgage.They will then talk of settlement.
It means that if they judge it to be better to take a settlement ,they will.
But do not forget they have more experience of squeezing money, so tread carefully and try to have everything in writing.
I do not know how much you owe or your circumstances but hope this helps
