Computations are carried out by taking into account vacuum condensates up to and including terms of tenth dimension. The dominant $S$-wave decays of these tetraquarks to a pair of conventional $ D_{s}^{+}D_{s0}^{\\ast +}(2317)$ and $D^{+}D_{s0}^{\\ast +}(2317)$ mesons are explored using QCD three-point sum rule approach, and their widths are found.
