Blacklisting a phone***

There is no emergency prosedure to black list a phone. One of my worker's phone was ****** yesterday on the 16th of December. I am on holiday and the phone's box is at my house. Phoning the Vodacom branch I always do business with I was told I must come in to the office. I am 820km from the office and the worker is 220 km from from the Office. Using 082135 did not help either. All I wanted to do was to blacklist the phone until I could collect the box that the phone came in and go to the Vodacom office to finalise the blocking.
