The UKVI site reports the following...
So if you have applied for a long-term business visa, the maximum wait is currently 30 days. Note that this is at odds with the VFS page...
Which says 90% are processed within 15 days. In either case since you signed up for SMS alerts, you would have had at least two messages by now: the date your application was entered into Proviso and the date your documents were assembled for the decision-maker.
If you have not heard anything, you should contact your VFS and try to confirm that your application was indeed submitted. You can also try to upgrade your application to priority if you qualify.
Finally, if you used a go-between travel agent to present your application to the VFS, then you may have to consider contacting the police.
