Vodacom messes up my samsung more

I am a very upset customer that doesnt usually escalate things but this time im very ****ed I have a Samsung flip 6 that i was ensured is now better in not having screen proolens like the 4/5. I have recently experienced my phone not sensing meaning the phone was perfectly fine but just the touch didnt work. Used the from screen perfectly. When i went to query it they said its still under warrenty so can be fixed. I purchased it a vodacom so took it there. They booked it in and later called me with a 12k+ qoute. I declined it as i dont have that much funds to fix it. They then returned it and i had to pay 200 rand still. I took it to samsung and after the technician didnt even pay much attention to me but other people he switched it on and told me my warrenty is no longer valid as the phone was cracked in the front screen and the lcd doesnt switch on just flickers black and lines. At this point i was fuming as there was zero cracked screens or did it fall when i gave it to vodacom. I also took the phone in its box but they didnt want to accept the box took it as is. The very only thing my phone did not it do is sense when i touch to do anything. I am very angry as i dont have the money to fix it and now dont have my phone. Warrenty has become a **** if it comes with so much ******* not even in a fine print or explained. The fault was the phone not me and vodacom repairs messed up my phone further, including the technician saying there was ink spots which was never like that when giving it to vodacom. Ive been a loyal client to vodacom for years!!? And used samsung most of my life as they are by far the best. But this is so so wrong and i cant explain enough how angry i am and need this sorted out ASAP and need guidence as im loosing out on work i need my PHONE

Please can i be advised where to go or to actually be helped, for me to get my phone back!!!!!!!!

Im out of words for both the company's now

Please assist Kind regars
