I have with a credit card company, it was within 2 months of the original query I logged, it proved my case and I got a refund and compensation.
I don't know the statute on length of time for the calls to be retained but I see no reason why it would not be as long as other customer data retention.
On a role I had previously for a loan company we recorded and stored all phone calls for 7 years. Now with GDPR that might be considered too long.
