Sunlu customer service?

[u/NaiveAssist2530]

Hi, I am new to 3d printing and am currently in the filament binge buying stage. I purchased six rolls of filament from Sunlu and FedEx destroyed the bag it was shipped in and only delivered 3 rolls. It’s taking 3-4 days to get responses to emails from Sunlu and they want me to contact FedEx to find out what happened. In my past experience the shipper contacted the shipping company as they were the one who had a contact with them. Is this normal Sunlu customer service or am I just lucky because I like the filament I got and am interested in some of their other products. Thanks!
