POOR CUSTOMER SERVICE

I'm retrenched end of August and I did Credit card Claim on September 2020 till today I didn't receive any feedback from them but they call me every month for payment. I went to the bank they said they don't have access to check status of my claim, they put me on phone for Call Centre, they were transferring me to one onother they said same story they don't have access to check status of my claim.
