Vodacom advertising **** specials

I'm disgusted by Vodacom's treatment recently. I took a new contract in January of the LG Q6 that came with a fre K10, the sales person who was assisting me told me that for my Q6 if my phone screen cracks I can bring it in to be fixed for free. In June my phone fell and the screen cracked, as advosed I went to East gate where I bought the phone, firstly I was told the sales person no longer works there then they checked my contract on the system and said it doesn't state 'Free screen insurance' , the LG lady refused to take it in and said she'd escalate to the store manager Keneilwe, she called me and told me she also can't assist because the sales person is no longer employed there and their records don't show free insurance, I asked her to escalate and she called back days later to tell me the area managers also can't assist. What BULL**** is that??? I asked her how it was my fault that her staff did not include the free insurance and she couldn't answer me. I also asked what was the problem with assiting me if they were aware of the period the special was running for which she confirmed that it was during the period that I took the contract and she still couldn't give me a conclusive answer. As if the ridiculous data charges are not enough yal have the most useless staff ever but come payday ypu don't forget to take money???.
