No service for 10 days

On 2 july my husband cut the fibre optic cable digging the garden outside the living room. The cable had been fitted under 1 inch under the soil. I wfh and had to stop working. Called Virgin. Took them 3 days to come out to confirm the cable had indeed been cut. The engineer said it should never have been fitted so shallow and he would prioritise it as I hadn’t been able to work. There were a team only 2 miles away who would be out that day or the following day ( Saturday) 

Nobody turned up. Made 3 calls on Saturday to be told  someone would definitely be by 6 pm. They had escalated it to the highest level.
At 8 pm received a generic email telling us the appointment had been changed to Monday 8 july. 
At 4 pm on Monday no one was out so called again. Was told that the local manager was not responding to any notifications and they could do nothing else . No one came on Tuesday and on Wednesday I texted the first engineer who confirmed the cable was cut. He said he would send the information to his boss. Over 24 hours later and still no contact . Received another generic email saying i was being compensated £30 as they had missed an appointment and to contact them if still needed an engineer. 
I can honestly say that I have never experienced such poor service from any company. I have been unable to work which they have been told numerous times. 
Can anyone help as I feel I am about to explode. No one takes ownership and we have absolutely no idea what to do next .
