One person tweeted: "Came home early from holiday, staying in Glasgow hotel to attend rearranged gig, my eight-year-old is devastated, was booked for her birthday."

Another stated: "Sam, my daughter has been waiting for months for this, after the last let down last month, how can you do this? You said you were ill, then travelled Europe, you are a wrong yin."

A third person commented on Facebook: "I won tickets for this concert through Concert for Carers as a thank you to NHS staff .

"After last month’s postponement how disappointing that the excitement of winning has once again been short-lived … oh well."

A fourth asked: "How do you get your refund then? This is a disgrace the night of the show again."

Other fans have wished Sam a speedy recovery. 

One person tweeted: "I understand the fans' disappointment and sadness but this is not Sam's fault, please be kind with them.

"I can't imagine how hard it would be for them not to be able to do what they were born to. Get well soon."

Another said: "Hope they feel better soon but I’m so disappointed.

"Hopefully I’ll get the opportunity to see them at some point."

A third agreed: "I'm absolutely gutted, first I can’t see N-Dubz now I can’t see Sam. I may never get the chance to see them perform now and as heartbroken as I am I really hope Sam gets better and they will be okay.

"Sam's health comes first. I pray one day I get to see them, get better soon Sam."
