Cam belt gone after 19000 miles

Hi all

Friend purchased a Suzuki 4x4 some 20 months ago. The garage replaced the timing belt, pulley and water pump as part of the sale (all listed on paper work).

Now, some 19K miles later the belt has snapped.

Should they contact the seller or are they wasting their time?

• Note: seller is in Sheffield and buyer is in the Midlands.

Thanks in advance.
