poor customer service

I tried to apply for a store card on several occasions and was declined immediately. Today I decided to inquire why am i getting the declined. To my dismay the agent advised that my account has a block as I did not pay the account. I was under debt review and this account was paid up Dec 2017. The credit bureaus has been updated already .I emailed the proof now . Both times I called I spoke to Tenesha( not sure if that name is correct as when i asked if that the agents name, the agent had attitude) , both times the call got cut when transferred to recoveries .

This is really poor service , from agent, on the send time she knew it was me as she didnt even try and assist me.

I sent both paid letters( loan and store card) on 21.12.2017. I emailed queries on 06.04.2021 again about a decline status but got a generic email response about affordability.i emailed my paid up letter again today. Please sort this out asap....
