Vuma Serviced incorrectly cancelled again.

Hi Vumatel. For the 3rd time in 18 months my ISP has canceled my Vuma Service due to a system error on their side. What frustrates me the most is that the address for the service does not tie up between your system and their system. For the third time I am being told by Vuma that now a new service must be ordered and I must wait. Last time this all took 16 days to resolve. I cannot understand how Vuma's system allows this error to keep happening and why I must was 2-3 weeks for my connection to be resolved. Can someone PLEASE be intouch with me to urgently get this resolved. Thanks Dani
