DONT BOTHER WITH VODACOM!!! WORST SERVICE EVER

I upgraded 6 days ago and was delivered a new Apple Iphone 6s after being contacted and told that due for an upgrade. All went very smoothly and phone was delivered the next day. From the minute I used the phone it kept on freezing and have to do a hard reset every single time! My Vodacom upgrade T&C explains on the contract that an EXCHANGE can be done within 7 days. NOT SO - they come and collect and then I HAVE TO CONTACT THEM TO TELL THEM IT HAS BEEN COLLECTED 2 days later and everything has to be reversed! <br> <br> I THEN HAVE TO GO AND RE-APPLY AND DO EVERYTHING OVER?!?!?! Good bye Vodacom, after 20 years you you have left me with no alternative but to go elsewhere.
