i was with simple debt solutions , creditfix has bought it out

before the new company took over it was agreed that i had only 12 more payments to make in to the iva one of which i have paid , can the new company make me go the whole term of the iva. the iva was for £19250 i have paid in at present £26,050 with another £3,350 to go

i am in an IVA, in my fourth year. I have paid £14,000 for the PPI and have been told that somebody else is taking over the company and the fees are going up so I am very concerned about this.
