VODACOM / SONY!!!

I bought a Sony Xperia Z3, the flagship phone from this company though Vodacom. After a lot of issues with the deal, I finally got the phone. Not even 2 months later, the back glass panel cracked spontaneously and I had it assessed and fixed under warranty though the advanced repair center. Not even two weeks after the repair, the back glass panel was apparently loose and coming off the actual phone. I immediately stopped using the phone and the next day took it in to get it repaired again. Now, after spending 2 hours in queues at Vodacom World, they prioritized the repair but that does not actually mean anything, they can't say how long it will take, they sent a mail to the technician but that also does not make a difference. This whole experience is leaving a bad taste in my mouth, and I will never again get a Sony Mobile phone, I don't know why I even bothered, and the service from Vodacom is appalling to say the least. Calling *** does not help at all. I need a replacement handset a.s.a.p., I can't be without a phone for 2 weeks at a time, and will you remove the handset subsidy off my bill? I think not!!! It's like this phone breaking is a normal thing?!
