Hi
Well firstly you will no longer be alone because you have found the site that will help you and support you.
There have been many poor experiences of Synergy posted on this forum as I'm sure others will tell you about.
I presume that you are paid weekly ? and when you send in your payslips you are asked for extra by your IP if it happens to be a five week month ?
One solution is to multiply your weekly wage by 52 and divide by twelve,this is your monthly figure and the one that should be entered as your income for your income/expenditure sheets.Ask your IP to use this as the benchmark for checking your income.IPs normally check income on a quarterly basis and this should even out the ups and downs of the weekly pay.
I would guess that a junior member of staff is checking these figures and you need to fight your corner.
