There seem to be quite a few online-shops which offer huge cash backs
for mobile contracts, often to the degree that there is hardly any
subscription to pay, plus you get a new mobile. Sounds too good to be
true. The small print then states that cash back will be paid in
instalments over the length of the contract. This means that if the shop
goes belly up, there will be no more cash back payments. Are these
offers generally trustworthy? I am somehow suspicious this could be a
scam. Are my doubts unfounded?
