Matter of lossing my job

Ive made numerous attempts to get a hold of some assistance from a team leader/manager to this day I've received no call. it's been 3 weeks almost and there has been urgency to install the fibre. My calls has been dropped and when I get a hold of the consultants they drop my call when I request to speak to their team leader for help. It is expected of me to work from home thus the application, my work place has gone as far as to give me some leave days to sort this out but I'm not getting any results or communication regarding the installation of the fibre at my home. Please supersonic I don't want to loose my job because of this.
