I just live chatted with a "senior specialist", they have now reffered me to the complaints team and offered me a £50 voucher..
Should i keep pushing this "specialist"?

Well done, at the very least you've profited with a voucher.

After the voucher was offered, how did the conversation end?

Order Value was 1000, Im not gonna let them off with 50, ill push this agent to the max

Yes of course push them for a full refund.

I just wanted to establish how the conversation ended to determine the next course of action. Though, It sounds like you have It under control.
