Question about two separate discounts

[#1]

I presently have a discount applied to my account related to the BT Share offer.
I am also due 3 months free - referral offer.
Will the the referral offer start when the BT Share offer finishes or will it supercede it

[#2]

After 5 days I think a bump is called for

Hi Jim,
Sorry for the late reply, I'll go double check for you but on first impression from checking the discounts on your account they should supercede the BT share offer.
