Issues with Furlough payment amount

Nikster73

Im having an issue with our accountant.  In Jan 20 I was paid a lower wage than my normal monthly salary, as I was attending hospital appointments that month.  Then in February, I was on SSP due to having surgery.  I was also on SSP for March's salary.  My sick line was up until 13th April.  If it were normal circumstances, I would now be working full time receiving my normal monthly salary.  The accountant has advised me that I will be furloughed on the amount I was paid in January.  For example:-
January salary - say £500
Feb salary - £441 ssp
March salary £441ssp
April salary would have been say £1000 but accountant is telling me my furloughed amount will be based on the January £500 amount.  Is this correct?
