Poor customer service

I have two vehicles with this company for 2 years now and requested them to have both vehicles(2) under one profile or account number which I have with them, but they failed to complete this request, secondly Netstar is failing to send me both monthly statements for the 2 vehicles every month, instead they send one statement meaning I have to guess my other statement. I have highlighted for 2 years now how this is causing confusion to making payments but nothing is being done. If you call their customer care the phone just rings for long hours without assistance or even your calls being returned. Emails for customers query are automated response. This company has poor customer service and cause unnecessary arrears to monthly bills. Their self service online app and whatsapp is zero effective. Regards
