I left work to go back to uni in september so had to give up full time work. I contacted lending stream to advise them of this and offer a repayment plan of £30pm which they accepted. I paid this every month but noticed I was accruing a lot of charges and contacted them. They said because the repayment plan wasn't set up over the phone it wasn't valid. I challenged this as it doesn't state this anywhere in my terms (and is a nonsense excuse) and they agreed and said they would remove all extra charges. I have stuck to my repayment plan but they then removed my option to repay online.When I contacted them they gave me another made up balance with hundreds in extra charges? They keep ignoring me when I say the plan has been agreed twice now and just keep telling me to phone in. Both times I was on for twenty minutes trying to explain with the advisor not having a clue (english not first language) and not even being able to find my loan. I'm at my wits end. This was agreed in October and again confirmed in December I've stuck to my side every date the £30s due so why aren't they letting me pay?! Where do I go from here?
