Forged Prescribed account by MBD .

My account bought by MBD prescribed in May this year.And I never even once spoke to them.Seeing the account prescribed and removed by Experian.MBD **** saying I paid the account in May but I didn't and I m in arrears fir 1 month in order to revive the account!!@ Why would I pay on the month the account prescribed???I contacted Experian and they said they will investigate but after 20 days they ruled against me sending proof of some sheriff letters no proof of payment from me,yet they still ruled against me.I guess Experian.MBD really works with Experian and will never win against this.The same Experian that removed me because of prescription put me back a month later.Does it make sense???I ll be laying complain with NCR and Credit Oumbadsman.This two companies must be investigated.
