Chery Century City

i regret ever buying an Omoda from Chery Century City, i bought my car in April 2024 paid cash only to discover in June that the service plan, warranty and Roadside assistance had all been initiated in June 2023 and the Sales executive who sole me car claimed he did not know that the service plan warranty and roadside assistance was initiated in June 2023 which i find very hard to believe and now means i have lost 10 months of my service, warranty and roadside assistance i in two minds to take my car back and ask for refund
