Contract says uncapped - I am being throttled

Please don't get us to sign and pay for contracts which tell us that we have uncapped internet, Mweb. Something has changed. If you are not happy with how much I am downloading, phone me. tell me that my contract is no longer valid and that the terms we agreed to no longer exist. You told me that I have an uncapped service with you - now in the middle of the service contract you change the rules. YOU decide I am no longer uncapped and you don't tell me. Tell me that I am capped. Tell me how much exactly I am allowed to download. Don't secretly throttle me behind my back. Please contact me and let us discuss a new contract. I am happy with Mweb - I have always liked them - but this is a new development that I'm not happy with.
