Major delay in refunding claims

I submitted a claim on the 6th of Feb, I phoned on Wednesday only to be notified the claim has not been processed. It gets escalated. I phone again today, only to be told I habe to wait 2-3 working days again. This has been the process with all my claims submitted this year. I have to constantly follow up with Discovery to get a refund and then I have to wait a week plus for you to do so. This is unacceptable!
