Home-Connect lack of service & response

We placed an order with home-connect, they gave our details to open-serve, with the incorrect address.

We were contacted by open-serve this morning and they said they'll correct the address and get back to us, but 6 hours later nothing happened.

I phoned Home-Connect as the error probably stemmed from their side and also because it's not possible to phone open-serve.

I phoned a total of 8 times, when you select the Operations option it rings and rings, then cuts you off.

I send an email and I also chose the option form somebody to phone me back, nobody phoned me back.

I spoke to Happy from Support who also said that he will get somebody from operations to phone me back - nobody phoned me back.

I finally got hold op Abudela from operations - who assured me that the wrong address shows up as our address - this isn't really possible as it's 2 streets on from us but the same number. She said that she will get into contact with Open-Serve to call us back.

Nobody has phoned me back.
