Number deleted without consent

Contract notice given to Altech as contract was up. Notice given on the 16th May, when I went into Altech a few days later Kershan that works at Altech had not read my email and it had not been sent through , he has not been very helpful nor clearly done his job correctly . I was desperate to move to vodcom as there service and reception is better. Vodcom tried to port the number a few times with no success as the notice was not put through as requested by myself by Altech.When port request came back each time the network declined the port. Today I went to try port to vodcom again and again it was declined. I was told my phone was transferred to prepaid and was able to be ported. So once again vodcom tried to port and about 1hour later my phone went dead and my number then said the number you have dialed does not exist I then sat at the Hillcrest branch Altech and was eventually helped by a really helpful lady Vanessa who then informed me that my number no longer existed on the networks it had been completely deleted. This is a huge problem for me as my whole business for the last 20 years has run through my cell phone and my number. This is my livelihood. I am devastated.
