I completely understand the sentiment, but the two issues are inextricably linked. As @Elliot correctly points out, the amount of pay and benefits that Motability reward their staff has a direct bearing on the APs that we pay. If their pay and benefits were in line with other call centres, APs would be lower – and possibly by a decent amount!
And with 80 new staff on a minimum of £36k + perks, that got to be paid, it going to imperative that outside deals are cross refrenced before commiting, especially if your going to be one of those who have to also take into account VAT – The R4 deals are proof of that, even now!
