No response to installation complaints

On 11 February I complained to Afrihost my ISP regarding the damage that the Vodacom installer did to my brickwork on my driveway ramp. I also complained regarding the installation fee (since resolved). Ref [#SJM-***8]. I have twice followed up, no response received and no action taken. Ghosting of customers does not work for me. Vodacom state I must action via my ISP.
