Poor service from Absa contact card

On 10/1/2018 I requested contact card to supply me with the closing dates for their credit cards for 2018. On 11/1/2018 received a request from contact card to supply info to verify identity. On 11/1/2018 (within hours) I rep**** giving the info requested. I sent follow up requests for a reply on 15/1/2018 and 17/1/2018. What kind of service is this, they can respond within a day requesting additional info and after that they just ignore all e-mails.
