Bad bad service

Vodacom operates as ******** for real , I bought a BP fuel coupon since 21 August 2022 and we to BP Tshepisong to redeem it on 24 August 22, i got a receipt to say Sale captured but petrol attendant along with cashiers said they don't know how to redeem on their BP system. Spoke to an useless Manager Nonhlanhla . I escalated the matter with BP countless times and there was no assistance from the head office. Went back to Vodacom to request my refund around 30 September 2022 but to my surprise the request was not logged. I called after 14 working days later they only logged it 21 October 22. Today 11/11/2022 did follow up I am told politics of Vodacom and BP. No clear answer for my refund still waiting.
