Waiting 5 months for my dishwasher.

I have a policy with ABSA where all my appliances are covered. I reported my Dishwasher in the middle of June and they send someone to come and repair it. They took the dishwasher as it couldn't be fixed it on-site. Since then I have battled to get anything out of them. I have spoken to ABSA repeatedly but nothing was ever sorted out. At some point the company who took the dishwasher told the bank they will bring it back within the week, but nothing ever came of that. This after I had to phone ABSA and hold the line while they phone them. After that they always said they are waiting for parts. ABSA send them again when I reported a broken box freezer and they took a month and a half to fix this. I am not satisfied with the way ABSA has been handling my complaints. They have not done anything to solve my problems. I have been without a dishwasher for almost 4 months. This is unacceptable. If I do not pay my premium for one month they will not cover me. But they can make me wait for as long as they please. I feel it is ABSA's responsibility to sort the issue out because they are contracting the work out to these people who are not returning my dishwasher.
