You don't say which strap you have but I believe the Elite strap has a two year warranty, as a result of well-documented failings.
However, Oculus don't really do a good, comfortable and reliable strap so I'd recommend buying one of the many third-party replacements available online. I use a BoboVR M2 which cost about £17 from Aliexpress or roughly double that on Amazon.
