MIWAY INCONSISTENCY

So MIWAY keeps serving me letters that my car insurance claim has been rejected because i have failed to send my car in for assessment according to the time frame given???? Firstly, i was told i need to book my own face to face assessment with Renew- It , which i did online and only a date which was on Monday 11th March was available. I accepted the date and time provided. Thursday a lady from Renew- It called to ask if i can bring it on Friday, i did mention i have work commitments and i would try to make it then, which was not possible due to work commitments already! This claim consultant Lerato Pilane now sends me correspondence that this claim is rejected because window period has lapsed and now another Judith Maluleke sends me the same??? EXCUSE ME! I pay my premiums and adhere to requirements now i must accept this behavior because these parties are not talking to one another??
