Clientele cash back not paid as promised!

I have a hospital plan with Clientele since 01 June 2014 and this policy included a cash back benefit of 6 months premiums after 5 years of having the policy. Since 01 June 2019 was my full 5 years with Clientele, I called them mid June just to find out about the pay out process. I was told that yes it does reflect on the system that my cash back is due, the payment will occur automatically before the end of June 2019, I don't have to fill anything. Today is the first of July 2019 and no payment have been received from Clientele, I called again just to find out what's happening. I'm now told a different story that I will get the payout between the 21st and 24th of July 2019. This is totally unacceptable as I'm always up to date with my payments for this policy, not to mention that Clientele is the first company to debit my account on my payday, they don't make a mistake. So now why should I wait for another month for me to get back my cash back as it is part of my policy agreement and not a favor from anyone? I would like to be assisted to get this payment as a matter of urgency NOT on the 21st of July.
