Unable to purchase data bundles

I have a month to month data subscription. Which is when I am running out of data I do purchase my other month to month, or whatever I need. Now since Saturday I am unable to purchase data, because You are already subscribed to MY MEG 500 SUBS Data subscription bundle. For additional Once-Off bundles dial *111* or SMS a keyword e.g My Meg 500 to 100". Why now Am I living by these rules, its my phone, my data, I purchase it when I need it. Why now this damn thing? Remove this from my number I want to purchase data, I am not going to be told what I have to buy. Secondly what is the use of your 082 111 when you cannot talk to an agent? Remove it so that we know we cant log calls. And that's is why Am on this platform because you CC is dead... In the next 24 hours I want to buy my data and month to month without restrictions
