iPhone 6 cannot be repaired

I took my two months old phone in as it had a malfunctioning touch screen.<br> I then got a loan phone without internet and e-mail that I had to pay a fee for.<br> I was then called in three days later, that phone is fixed.<br> I was glad but after a couple of hours the problem started again<br> <br> I then took the phone to iStore in Walmer to do a diagnostic report on my phone so that I can submit it to Vodacom.<br> I then submitted the phone, It has been a week and two days, <br> Used the online chat and I have been receiving the same answer we will ask the person busy with your repair to contact you.<br> Till today I have not received a word from Vodacom Repairs, they have the most slowest and worst service I have ever seen. I regret buying this phone from them in the first place and it is for the last time.<br> <br> My phone is a Silver iPhone 6 64 GB<br> The REF number: A1-X3RV-JUGYB (from Vodacom)<br> My name is Phambili Mapolisa<br> Cell number ***<br> ID number: ***
