Incredibly bad repairs experience

I purchased a Blackberry 9720 Pink online from Vodacom on 18th November 2014. One morning on 18 May 2015 my phone just was off when I woke up. It would not switch on at all so I took it to Vodacom at Woodlands who took the phone to send in for repairs. On 26th May I received an sms saying that the phone had been returned to Vodacom Woodlands. The repair invoice stated that the LCD connector was damaged but they are not replacing it.Also my battery was not returned with the phone and I had to request that they return it. I was also advised to maybe get someone to try and repair it privately!!!!!! I was not at all satisfied with this service as the phone had a technical error(LCD connector is part pf the motherboard internally), and they would not replace it for me leaving me with a contract to pay and no phone. I have been in contact with Vodacom repairs helpline- the latest being the 3rd of July 2015. The lady assisting me (Miyelani) said she would need to follow up and promised to get back to me- not a word from Vodacom yet. I am frustrated as I feel Vodacom should honor their warrenty and replace my phone.I am now fed up and hopefully can get my problem resolved in this way!
