Isa transfer

I opened a fixed rate cash ISA with NatWest 2 months ago. I already have one cash ISA with them at a lower rate. They allowed me to open the 2nd then closed it as I didn’t realise I could only pay into one cash isa in one year ( and had already paid £2000 into my original account) Can I now transfer my isa allowance into a new account ( from my existing Nat west ISA) and still use the remaining allowance? Will the £10K I invested in the new account be counted as part of my allowance, even though I wasn’t paid any interest? Thanks

Hi
Please refer to guidance at :
Individual Savings Accounts (ISAs)
Thankyou.

Thanks but I have already looked at the link & it dosnt answer my question. If Nat west ( wrongly ) allowed me to put £10K in a new isa then subsequently closed it, would that £10K count as part of my allowance?
