SH ongoing BAD service delivery

Discovery Health is really bad at making payouts. I regularly visit the Chiropractor which I pay for in cash and then submit the invoice for payment to DH. The message coming back clearly states that he request will be processed in 2-3 days. This is simply NOT true. It has taken upto 3 weeks on occasion for payment, this being after I have re submitted the claim 3 times. This is totally unacceptable as it happens every time. I would HATE to see how long DH takes to make payments of large amounts for operations etc. The service of DH has really deteriorated in the last 12 months. The most unprofessional service ever.
