Upgraded but services not loaded

I upgraded my Vodacom contract during July 2015 online (phoned and did the upgrade over the phone). I upgraded to a R150-00 top-up contract and when I requested the call centre assistant that she must please add a sms bundle as well, she indicated that she is loading a sms bundle for me with 100 sms's for FREE on a monthly basis. After the upgrade was done, I had to phone every month for them to load the sms bundle which they did. When I contacted the call centre last week enquiring about the sms bundle that was not loaded for the past two months I was informed that that was not included on the contract as advertised. I know it is not advertised like this but it was allocated to me by the retension department. On 23/10/2015 I bought an additional 250 megs of data from the local vodacom shop. On their system it shows that it was loaded but I never received it. I contacted Vodacom and when I asked on what it was used they could not tell me at all. I use my phone / data mostly for Whatsapp and doesn't use it to go on the internet. I received 500 megs on 01/11/2015 and today when checking, I only had a bit over 300 meg left. Please assist as the call centre can't
