Fibre Problems

What i thought would be a simple transfer of my fibre line from one address to another has turned out to a be a frustrating, money losing due to work commitments that could not be kept, and mobile data that had to be purchased. I have heard different reasons for this delay from previous client not cancelling properly to vumatel line problems, none of which solves my problem with it becoming ridiculous when a consultant tells me that he cannot call the previous client to get line released.
