Did you try getting in touch with the seller again asking him if he is still interested in getting the card repaired?
Been telling the buyer a lot many times, giving him offers, but he is not willing to agree upon anything, rather just keep spamming "Seller is a scammer" on this thread.
Despite him threatening me for official warnings, legal cases, consumer court, justice court bla bla bla, I am still politely offering him options to pick from, but if he does not agree, I am no longer interested in reaching him out any more.
There have been over 50 people who have dropped their opinion on this thread, some favoring the buyer, while others favoring me.
I believe I have done enough to show that I'm not scamming anyone, nor here for fraud sales, and made it all clear what I have got to offer, and left the decision on the mods and the buyer.
Sorry it is not possible for me to go and lick the buyer's feet saying please let me help you and sort this mess out, nor I will beg the buyer to remove his fraudulent reviews from my Google Business page (how tf did he even come to know that, is he stalking me or smth).
I have stated lots of things by now, and I believe I have been a lot polite despite his unruly behavior and his inputs regarding this matter.
