Worst experience regarding insurance claim with Momentum

At this moment I am really not happy with Momentum, from the moment they took over Alexander forbes my insurance is only causing me headache! I have a claim that have not been processed for more than a month now even though I took my vehicle to the appointed assessor. They do not respond on emails and calling them is just as useless because everytime you speak to someone else whom does not have a clue what they are doing. This is really unacceptable and unprofessional to say the least.
