Shocking non-service from Old Mutual Rewards

I am terribly disappointed by the non-service from OM Rewards. On 14 Nov 2025 I informed OM Rewards that I was not able to use my OM rewards voucher that I had activated on 13 Nov 2025 to book flights. I kept receiving a message that the voucher was not valid. I requested assistance. Since I received no feedback, I followed up a week later by email on 20 Nov 2025. Zachary Rhoda of OM Rewards informed me on 21 Nov 2025 that he had logged a request to reinstate my voucher and would give me feedback as soon as he received it. Since I had no feedback for a month again, I followed up by email on 19 Dec 2025 and requested feedback. Again NO reply, My conclusion is that OM Rewards does not care for their customers. It confirms the advice of two financial advisors who independently advised me before this experience NOT to buy retirement annuities from OM since it is an administrative nightmare. This latest experience confirms their advice. Rather take away my investment with OM, and deal with other institutions as my retirement comes up in a year.
