No After sales care

Bought a Vodaphone E8 for my son as his first phone and after having been to 3 vodacom stores, a china mall with 4 cellphone accessory shops and your vodacom website i havent been successful in finding a cover for it. I chatted to a online consultant and she said they stock them in store but cant tell me where. Im ever prepared to drive to vodaworld to find out if they might have the cover and you select to speak to a consultant it says subscriber unavailable. This has been a terrible experience with vodacom as a whole. Plus now we are locked on the network with the cellphone i bought.
