Momentum is avoiding to pay my claim

Was involved in the accident on 18.04.2015,momentum came to my adress to take the car on 22.04.2015 for assesment.Each time i want the update to my claim the claim advisor(Phaladi) did not respond to my email for about 3 times.I even copied his manager Mr love he also kept mum.Until i phoned then started accusing me that i give him the wrong info when reporting the instead of giving me the update.Later on the matter was handed to further investigations.The investigator is Ettienne van Merve.According to them the matter was handed to him on the 30.04.2015.This matter is been with him for almost 3 weeks & i asked him by email last week he said he's in the process of finalising the claim.But today when i ask him he's saying i was not driving the car when the accident happend the lady was driving.Of wich i explain to him that i was driving-even if she was driving she's got a valid lincence obtained in 2010.Its been a month now this matter is still not finalised.Am so incovenied & frustrated at this
