Uber eats cancelled the order and no refund

I placed and order on the 29 September. Uber eats cancelled my order after waiting almost an hour. There Help center is pathetic as they communicated that I should make contact the 3rd party payment provider to advise when the refund will show in my account, which I did. The payment service provider confirmed that Uber Eats received my payment but no Refund was actioned from Uber eats.. I communicated this back to Uber Eats when they responded the refund was made and that it could take upto 30 days to clear in my account. More than a month later no refund was made and they now stating that no refund is due to me.. I communicated again stating that there terms and conditions clearly states in the event that uber eats cancel my order the full amount will be refunded They then responded to say they will investigate the order and advise . 2 weeks later no feedback and no refund .. I'm definitely not using Uber eats ever again as I'm obviously not the only client the are taking money and not delivering the service U pay for
