Oppo and Vodacom poor service

After many years with Samsung cellphone, I decided to take out a Vodacom contract with an Oppo A74 5G, part of the deal was a set of Bluetooth airpods. The right side failed to work 1st time I used it, took it back to Vodacom branch in Baywest mall Port Elizabeth, they had long stories about repair policies, got the Oppo agent involved as well and said it will take 10 days to replace, went back after 10 days to Vodacom branch, they will follow up next day. Contacted Oppo call centre, what a disaster. Agent doesn't understand simple English and tried to refer me to repair centre, that was not my reason for the interaction, I wanted to report poor service received. Eventually terminated chat as I was getting nowhere as the guy didn't even read my complaint or understand. My greatest concern is the future service and reliability of the handset. If I knew the poor service, would never bought the Oppo handset. The service from Vodacom branch not much better, my wife noticed that if I take the said phone package I will receive a R250 voucher, agent said not on this deal while it is clearly displayed in shop, she eventually came up with an excuse and I received my 250 store credit. Not impress by both Oppo and Vodacom
