PhonePe — Regarding refund to flipkart pay later

Dear Sir,

There is a refund from phonepe to flipkart pay later of 276 initiated on 07.10.2020 and 762 initiated on 11.10.2020 but flipkart pay later have not credited my account. If I ask phonepe they are asking to contact flipkart pay later and flipkart pay later is asking to contact phonepe. Please do solve it
