Airtime purchase failed to be credited

I recharge airtime of N2,000.00 via myMTN App on 10/09/2024 using Bank Transfer Method of Payment. Transfer was successful but value was not credited to my line 08034502750

I purchased 1G data on the 27-12-2022 but I never received the data, secondly, today, 03-01-2023 I bought airtime of same amount via the same channel of *904# on my FCMB account...
