Broken main sewer pipe problem

NornIronRose

The saga of my leaky toilet goes on but at least the mystery is now solved. 

Had Thames Water out a few weeks ago to clear the blocked shared sewer. Great! Except the upstairs toilet started leaking again. 
Got drainage guys out and £335 later I now have a cleared main sewer pipe but CCTV has shown that it is broken. 
I've been quoted the guts of £3k to fix it. When I look on sites showing an estimate for this type of job, they all show around £200-500/metre. The distance from the manhole to the broken 90° angle is approx 1.5m. 

I have my house on the market and need to get it fixed properly. I know I need to get 3 quotes, but don't know anyone in a similar position to give a personal recommendation. 

Not really 100% sure what questions I should be asking. If anyone has experience of this I'd appreciate some guidance please.

Why is a broken sewer making your toilet leak?

How did 90 degree bend get damaged?

You say it has been a bit of a saga getting a blockage cleared, has someone been a bit heavy handed and been rodding into bend with bare rods while trying to clear the original blockage, if so could a insurance claim be made.

Check your policy and if you have legal protection call them.

Do you mean there is a leak upstairs, or that the pipe from the upstairs toilet is leaking underground?

I can't see how a blockage in the underground sewer could cause a leak at a much higher level - normally in that type of situation a manhole at ground level is the point where sewage starts to overflow.

The pipe was broken and sticking up at a right angle almost and waste was getting stuck behind it for goodness knows how long. At least, that is how it looked as the guy from the drainage company showed it to me on cctv.
My eyes were probably watering at the £335 bill that day with the promise of thousands more to come!
 Not sure whether it may have been damaged when Thames Water came out to clear the blockage a couple of weeks ago. That didn't occur to me. 

I know that they had cleared the other sewer pipe which had our downstairs toilet and sink waste running into it. But this is a stand alone one by the looks of things. Once the manhole cover was opened it was obviously blocked. Which did surprise me as I would have thought they would have opened all 3 manhole covers next door. 
This is onne pipe that comes down the outside wall from the upstairs toilet then is a 90° angle into the manhole next door. 

I didn't think insurance would cover it as I thought it would be a wear and tear issue.
