Unprofessional and rude

I am currently trying to claim for my cellphone I was told they will only process my claim after my next debt order date , I asked why not now because my debt orders went off previous months but the person in charge of my claim became very rude I then asked her to transfer my call to her manager who was also not much of help in fact she started shouting and screaming at me then hanged up on me. I sent emails to report this I got no reply. This is not the kind of service I was promised when they sold me the policy nor is it the kind of service I am paying for to be shouted at and dismissed
