Umbrella company NI deductions

Val999

I have been carrying out around 25 hours work a month via an umbrella company since November 2021. They have been treating this as weekly pay (with the consequent employer and employee national insurance deductions) even though this work occurs only monthly. I have just managed to get them to agree to a monthly pay arrangement but they are refusing to recalculate the earlier payments as they say they have already reported this information to HMRC. Can't they send corrections to HMRC? Is there any way I can reclaim the NI payments?

See https://www.gov.uk/claim-national-insurance-refund which I hope might help.
