Gujarat State Road Transport Corporation [GSRTC] — Ranpur Surendranagar Bus service - dhandhuka depo bus

Dhandhuka depo runs bus service between Ranpur - Surendranagar like circular route. Bus is running since 1994 or so.
Last couple of weeks but time table is totally mis-aligned. Every day in the evening bus starts from Ranpur to surendranagar at 6.15 P.M. but it runs one hour late daily. No solution found even after calling dhandhuka depo.
Please maintain timing at any cost.
one trip the bus goes to malampur and this route takes one hour time. there is no single passenger from either side. wastage of money. loosing regular passengers as well.
