Hisense HWFS8514E (8.5kg)

FO3 is the error message on my machine (HWFS8514E) that I'm needing help. I rang last week to get someone to come out and have a look at my machine as i was told it was a blockage. I was told the model no. will be on the door-WHAT! I can't open the door I told the CSO and she said she couldn't help until I had this info and hung up. I thought I might be able to release valve on the bottom right. I had buckets and towels ready thinking if I can get the water out, the door will open and I can get the model no. - this didn't happen but more washing did. So now I have a door that won't open up with washing in it plus now more washing. I rang back pleading to find another way to get my trapped wet clothes out. The 2nd CSO started nice starting a rapport with me.i explained the situation and she can help open the door with a knife. I asked her if something happens to my door am I covered? She wasn't sure. She said sometimes they put the model no. on the back. I advised her that it was a stacker so it was going to take a bit of time because it is heavy. The CSO became frustrated as I was going over 1/2hr with my problem so she also said that she couldn't help and had to go. I'm in tears now (which no customer should never be) I located the invoice and rang back for a 3rd time. I was given a name of the people that do the repairs but they weren't happy as apparently they had told you several times they don't work with you anymore. I then rang back to tell you this and was told I this was the first time they had heard of this. I now been directed to another repairer which would be great,however, you have sent me a message telling me that it will take 2 weeks to get a part in for my repair (FO3) so this will make it 3 weeks since I first asked for help. I would like if you can to reply to this review as I'm so angry.
