New Customer - Pre Install problem - Hardly any support

Hi, new cutomer here, hoping for maybe some answers, but wont hold my breath.

I placed an order for virgin fiber 1 gig last week, during the process i was told they will need to do external work which wont need my attention, and the only time i needed to be there was for the engineer visit to go live. 

My install date is due tuesday 24th september, but i now have many doubts to if this will actually happen.

1) I placed order on friday 13th to go live on 24th september.

2) I was aksed during sign up if i had a continous drive made of soil, cement, paving, gravel to front of property and i said yes. (This was apparently so they could send the right team with equipment to do any digging work.)

3) I check on my virgin media and says all going well.

4) Monday 16th at 8 a.m 2 virgin engineers knock at my door asking to speak to me, so they could explain they are here for the pre install work.

I breathed a sigh of relief when they said they didnt have to dig up the drive way as they will connect my cable to the pole as they all are full fiber now. 

They said they just need to put a box on side of house and run a cable up to the pole. 

I said great thanks, and i am glad the job will be easier for you as no digging.

Within less than 10 mins they had both got into there vans and drove off and no work done.

5) I contacted virgin media that same afternoon and asked what had happened, and was told they will have another pre install team come out, the new appointment was for thursday 19th, between 8a.m and 1p.m.

6) Thursday 19th no engineer come, so no work done. Therefore a waste of me staying home as no one arrived.

I contacted the pre install team again, asked why no engineer showed up and they just apologised. 

Apparently some extra work needs to be done is all i was told by the pre install. I was told it would be escalated and that i will have another engineer visit for pre install for friday 20th between 8a.m and 1p.m.

7) Now friday 20th and although i still have time until they are supposedly coming, i don't hold much hope. so therefore i start process of asking on here what can actually be done. or how i can get more information on what is happening.

why is it the engineers miss so many visits, and yet the customer should wait at home patiently just for them not to arrive.

Also on the same day i placed my order that same night a guy came to house trying to sell me virgin products, and when i told him i had ordered that morning he hurriedly went to next house.

But the strange thing is i later find out he asked for me by name outside my house, and my friend said no he isnt. so the man speaks to me but he never calls me by my name. he just acts as a call seller.

I didnt really like finding out about that as feels like he was just there to gaurantee i had ordered that morning.

sorry for my rant, and sorry for any spelling or poor grammar.

would be nice to see what i can actually do about this, as i dont think my go live date will happen now
