Illogical reasoning for complaints not been attended too

I initially contacted Vumatel about an issue with my existing fiber line. A contractor was dispatched and, unfortunately, ended up damaging the entire fiber line during their visit. Following my complaint, a technician was sent out the next day to install a completely new fiber line.

However, a third person was scheduled to connect the new line to the Black box, which never occurred. Despite the work not been fully completed and me having no wifi, I was dismayed to find that my service ticket was marked as "resolved." Upon calling your call center, I was informed that tickets are closed as long as a technician has visited, regardless of whether the issue has actually been fixed, and that I would need to raise a new ticket because the cable was damaged

I find this policy completely illogical and unacceptable, especially since the initial damage was caused by your own contractor. Despite my attempts to resolve this with the call center agent, the issue remains unresolved.
