Worst Service from Rcs Insurance department

The insurance department is irrational and they take ages to respond to queries. I have a loss of income claim that was approved but i have now found employment and I've requested to remove the block from my account. They are giving me every excuse in the book not to remove the block. I've wasted so much of my airtime and personal time trying to contact them and liase with them. But surprisingly their team leader has either left early from work, or he is on lunch break
