Claim and Service

I don't know what kind of company does not care about their reputation. I have called, I have emailed, I have tweeted and I have complained on this platform and guess what no response on any of the platforms or acknowledgement. Instead what I get is collections calls. Like what the hell. I have put in a claim in May and nothing is being done. I have sent this more than once. I have called and nothing. All I get is stupid people like Raessa who answers phone like she is at her house. No branding nothing just hello. Then you get collections people like Mr Osalawadeen or whatever his name is who disregard what you saying and nip you. I don't know what I should do about this matter that remains unresolved.
