I had a boiler service and repair done in September through OVO beyond. Boiler was only providing around 20-30 seconds of hot water at a time and I ended up paying £230 for the flow control to be repaired which fixed the issue. 

However I now have a leaky boiler (Worcester Greenstar 30i) which is leaking from the front right corner, and a quick Google is suggesting this is also a problem with the flow control system. Therefore I can only really come to the conclusion that the initial repair was either done poorly or incorrectly. 

Understandably I've been told to turn the water off at the stopcock, but I can't seem to get through to anyone who can get an engineer out to repair it unless I wait until 8am on Monday to make a call. I've been told I can call the Gas Safety numbers but it's have to pay whatever the cost is for an emergency call out and there's no guarantee I'd get that money back/be able to make a claim.

From my point of view, the original work wasn't done to a high enough standard and after paying £230 for that repair only 6 or so weeks ago, this repair should be covered under a guarantee/warranty. To add insult to injury, despite paying all that money for a repair, the call centre at OVO can't find any record of the repair being done! I've definitely been charged for it, my wallet is much lighter, but it isn't showing up on the system!

I have two kids under 5, it's 9am on a Saturday, and I can't be going without water until Monday (assuming if I call on Monday they can get someone out the same day) 

I don't know what to do!
