Engagement Ring not returned back after resizing

I sent in my engagement ring which also consists of two bands for the wedding ring in for re-sizing 8 July 2015, and was told that i would get it back by Friday (10 July). Had i known they would only send the ring for re-sizing on the day i had to receive it, i would not have sent it in the first place. I had to attend my lobola negotiations without my engagement ring. I went back on Monday, as i was then told on the Friday that the ring had just left, it would be back then. Only to find out that the lady who wrote on the envelope, never mentioned it was URGENT. I never knew having a ring re-sized had to be an urgent matter. Needless to say, i didn't get my ring on Monday. It is now Wednesday, a FULL WEEK after i had sent the ring in, after being told it takes 3 days for the whole process. I had been waiting for them to call me back today, as they had promised they would after everything that had happened! I had to call them back, only to find out that the ring was back with them, however \because of load shedding
