incompetence

I took an Xperia Z1 Compact in for a cracked screen and unresponsive touchscreen to a Vodashop. It took a few days and I got a quote estimate via SMS from the Advanced Repair Centre (ARC). I promptly went into the Vodashop and accepted the quote. The lady said the she made a note on the system that the quote was accepted. I continued to get the quote SMS on a daily basis so I proceeded to contact the Vodashop again and they said an email had been sent to the ARC in JHB. I continued to get the quote SMS daily for the following two weeks and then on Friday 18 Aug I get an SMS saying that the quote was not accepted and phone will be returned without repair?!? I returned to the Vodashop and they called their technical department (who I had to talk to - instead of the their own employee). She said that another email had been sent to the ARC. A week later I got an SMS saying the phone was ready for collection. I paid cash, received the phone, plugged it into charge and... the magnetic charging port falls out. ***. What happened to QA? I know had to take it back again for something they broke. Back to the ARC. Must I wait another month? Lets not talk about the factory reset as well!
