Settlement issues - why must I still pay a instalment

I requested settlements from your debt review department and got settlements on my directaxis and one life accounts. BUT they charged me both capital and the next instalment - which is not acceptable.

My last statement clearly stated my capital balance ( same as my settlement received ) but stated I'm one instlment in advance.

When I asked if they can please escalate - I was told its company policy and I have to pay the instalment. I'm sorry - but you are the only company asking for the instalment still.

I'm in advance and do not have to pay an instalment this month

Can some one in a Senior position, please investigate - as I'm sure this is totally against the NCA , CPA and TCF policy ( yes, I know my policies )

Please provide me with feedback as a matter of urgency . I settled my accounts and require paid up letters - I need to know why you are looking for insalmetns - while I'm paid in advance.
