Where does the buck stop

WHERE DOES THE BUCK STOP. I have recently had fibre installed, the ISP is AFRIHOST the fibre is VUMATEL. BRITE LINK are subcontracted to VUMATEL to install the fibre. BRITE LINK then used their own subcontractor PETER to install the fibre in my flat. Peter made a big mess,( see pictures, he ran the fibre right around the walls)., so Vumatel then sent a different subcontractor GERRY to fix up the mess. GERRY did a good job, but my recently painted kitchen is a mess because of all the wiring and glue used by PETER. I complained to AFRIHOST, who logged a complaint with VUMATEL who told me I have to deal with BRITE LINK who in turn say PETER has to sort out the mess. I asked BRITE LINK who is going to pay the painter, they agreed to cover all expenses once the job is complete. The painter wants me to buy the paint, (he painted for me previously and this was the arrangement). PETER doesn't have time to buy paint BRITE LINK won't refund me ( and maybe not even the painter when the job is complete ), and VUMATEL say its not their problem and AFRIHOST say this is VUMATEL ' S problem.
