Herbalife BAD Service.

I don't even what to give this company a rating of one. After i was asked to join Herbalife as a member, i went onto there website to join. paid the fee ( all on the 4th June 2019. When i queried the next day why i never received any confirmation emails, i was told that i never registered. But app on checking my sponcers details realized that a payment was made via PAYU and not PAYGATE, (no where on the web does it state to use PAYGATE if you are signing up for the first time. Then they suddenly confirmed that they did receive my payment and i will be refunded, this was on the 5th June. One week later 14th June i checked in with the helpdesk as to why i was never refunded yet, the lady on the helpdesk was not aware that i had a refund due to me. I then gladly passed on all the confirmations regarding my payment and she again confirmed that i will get my refund. Today 21st June i have not heard back form them, i send an email to check for any feedback related to my incident. Still no response. Can someone please advise me what i should do to get my money back.
