Not receiving contract data or sms bundles.

I upgraded two contracts at the end of last year using your website. After the upgrade I received the promo 30gb data but since then I have not received ANY data or SMS bundles even though the contract I signed was supposed to come with 25minutes 50sms and 100mbs data.I have written a query on your website which just got ignored, I then emailed your customer services department (***) and only received a response to confirm my ID number etc for security purposes, I did that but have not heard anything back from them. I am sick of not receiving the data bundles I was contracted into receiving. I have proof on the original contract where it says I receive 100mbs data per month should you require me to provide it I will. This is pathetic service! This effects 2 contracts both on the exact same package, both with the same problem.
