Struggling with fault logged

I have a maintenance contract with Teljoy for my washing machine, dishwasher and freezer. Last week my washing machine stopped working and I logged a fault with Teljoy. I received a reference number on Wednesday 23 November. I had a contractor come out two days later to check. He said he needed to get a new keypad and will get back to me. Yesterday I called Teljoy. I didn't hear anything yesterday. Today I called again, but got cut off so I filled out a form on their website to get back to me. I was called back and got told that they're struggling to get hold of the contractor, who's apparently not answering their calls.

I am beyond frustrated as currently I have to travel to my daughter's house, do my washing there, bring it home to tumble dry and ironed. REPEAT. I need this sorted out ASAP.
