Umart RMA situation Sapphire 7900 XTX nitro

My sapphire 7900 XTX nitro GPU that I got in a custom pc build in august 2024 has seemed to die randomly i had only owned this pc for 3 months so far.

so i sent it into Umart for them to check and a few weeks later they got back to me saying they need to send it off which was on the 16th of November,

its now the 4th of march and i have not received any comms from Umart. I've been calling every 2- 3 weeks asking for an update and all i get each time is ''I will check with the warranty team'' and a new email thread starts,

is this a normal thing? it's my first experience dealing with this sort of thing 3+ months seems like a super long time to wait without an update saying it's even with sapphire.

what are my options?
