[Resolved]  Samsung — service related issue

This letter is to bring to your notice concerning the purchase of
Mobile on september, 2019.

After few months i getting trouble issue with the device and facing
Many issue, then i visited a near by service center i submitted my
Mobile for service and repair purpose but after some days he informed
Me that your device can't be repaired so we issuing a service refund
Coupan against your device (Samsung m30s 6/128 gb).

I got a service refund coupan against my device but i wanna to
Purchase same series device (Samsung m31 6 gb/128 gb) so i asked to
Many samsung store to redeem my service refund coupan against the same
Series model and give me the product but every one is decline, he said
This device is available for online sale only.
But how can i redeem my credit note against online purchase that's not
Possible for me.

I'm not ready and want to purchase any other model of samsung i want
Only samsung m31 6/128 gb, if possible then give me the same device
Against my service refund coupan or refund my full money in my bank
Account only.

I'm so much harassed by samsung service center, i lost my so much mind
And precious time about this silly matter.

I'm requesting the last time that i refund my money in my bank account
Or arrange the samsung m31 6/128 gb device against the service refund coupan.
