Poorly run promotions

so I received an sms yesterday saying Vodacom is running a promotion and I need to download the my Vodacom app and check a balance and I will received a gigabyte to use within 7 days so I thought this is a nice promo. so after I downloaded the app on my phone I tried going into it but got the error message \unable to log in check your network connectivity\". so I called the call centre this morning and the first lady I spoke to said she will send email configuration settings and I must reboot my phone. I never received this message and I didn't think to ask for a reference number anyway I called again and spoke to Khanya and she still was having attitude with me call reference number ***7 and she said iiiii aaaam asking iifff this is the number u calling from that needs resolution so I gave her attitude right back and she said she will send the settings and while I was waiting she was making noises like she is having an orgasm in the background to ridicule me. anyway until now I have not received any settings nor her call back which she promised. Vodacom needs to run better promotions not ones with glitches, I buy on ave. 20 gigs per month from u guys on my s6 edge, im disgusted"
