Overall bad service and experience from Vodacom

Good day. On 4 October 2017, I got my new iPhone 7. On 14 January 2018 when I wake up my phone died over night, how is it possible that a +-3 month old phone just died overnight? I took it to our local Vodacom Shop at Langeberg Mall, Mossel Bay and was told they have to send it away to be fixed. They asked for my iCloud login details to put off “find my iPhone” on the PC but was incapable to do it so I did that and even took a photo and they confirmed it is ready to be sent away for repairs. I received a sms that it will take 2-3 work days. After 9 days I received a sms that my iPhone is back at the branch. When I got there I met the most unfriendly and unhelpful staff in a very long time. I was told that my iPhone wasn’t fixed because the technician said that “find my iPhone” was still on. How incapable is the staff at Vodacom that they don’t know what is on or off? Clearly they don’t care about the customers! They just state it is my problem. I also found that they took off my screen protector, this wasn’t told to me beforehand. They just told me sorry not their problem, I must buy a new one… So must I now wait another 9 days just to hear “sorry not our problem”? I do a lot of work on my phone and that is why I got the iPhone in the first place, but now when I already struggle without it, I must also experience bad customer service from Vodacom. What happened to real customer service where the customer is number 1? Is this the way Vodacom do business?
