You are your own customer support agent as the customer

I order something almost 3 weeks ago and did not receive it because the courier kept delivering to the wrong address despite my address on my order being correct. After 3 attempts they supposedly sent it back to BASH(which I was ok with) I was told that I would be getting my refund. It has now been a week and I have still not received my refund, I’ve emailed them and they keep sending me (the customer) from department to department to resolve a query I came to them them, which baffles me because is that not their job as customer care/support? At this point I might as well be working there. I’m actually considering closing my tfg account after 1 month because I’ve not had one pleasant experience since opening it.
