Empty promises and let down AGAIN!!! Zero trust in my fibre provider to manage a simple relocation request

You would think that to manage a home relocation with your fibre service provider is a relatively straight-forward standard procedure, which can therefore be effectively and efficiently managed. I have had to relocate twice in the space of one year (already a major stress) only to have Vodacom mess up the relocation request - BOTH TIMES!!! This time round, they have openly admitted that it has been their "stuff up" - and I was then promised faithfully that my issue would be resolved, and that they would expedite my now NEW relocation request. I spoke to 3 consultants last week - each promising that the matter was taken care of and that they would prioritise my new relocation order given the fact that I have been messed around. So, I phone back to Vodacom this morning because I have received ZERO written confirmation of the discussions last week .... only to establish that NO NEW INSTALLATION request has been done - and so I am literally back to square one - now another week down the line! I work exclusively from home and am highly reliant on my fibre connection, and so here I sit paying exorbitantly for additional connection from my faithful Telkom LTE device whilst I pay for Vodacom fibre that I don't currently have. This is completely unacceptable service from an organisation that promote themselves as "top of their game". I cannot believe the terrible service - how can I ever trust what I am being told when it is nothing but empty promises, and further delays - and as a paying customer I sit without the service for which I am being billed. I cannot believe that I have been let down by them twice in a row!!! The added stress and aggravation I have to endure - yet again - is totally unprofessional.
