R150 voucher didn't get into my betway account

Good day I made a deposit of R150 on my account using 1 voucher the money didn't go through. It said invalid voucher, I contacted betway immediately, they escalated the matter & I was told I will be credit back with that money into my account within 24 hrs. It was on the 15th April 2023. Yesterday I was on a live chat & the agent was helpful he picked that the voucher went into another person's account which is not registered under me. He even made an effort to call & explained what he picked on their system but will take the matter to his manager & ensure I'm credited the R150 into my account.

Since the 15th to the 18th April 2023 I haven't been refunded& I phoned just now i had to hold til I ran out of airtime. I'm grateful of the service I got from agent Trevor on the 15th & agent Derrick on the 17th but all I'm asking is for Betway to credit back the R150 probably their system had a glitch. It's 4 days now still not credited .
