DELAYED, DISHONEST, UNRELIABLE

I’ve sent two emails, no response. Called thrice, put on hold twice, got through once. The one time I got through they told me they had lost the parcel and they’re waiting for it to get back to them and they should deliver the following day. It’s been a week now and I’m getting annoyed because this makes my supplier and I seem to not care about my customer. My customer also called in and they claimed to have delivered the parcel yet there’s been no call regarding the parcel yet. Just this morning as I called and I recited the tracking number, the woman on the other end put me on hold. I’m getting very annoyed now.
