Need a refund or fix the problem

A week ago I bought myself a telkom data bundle wich were R279 uncapped for 31 days I have been using it for awhile but the download speed is slow but before I get there before buying the package I read that is says 250GB at 10mbps thereafter 50GB at 4mbps then 2mbps unlimited for the remainder of the 31 days but when I bought the data I received an sms saying uncapped at 2mbps and when I download movies or TV series its under 2mbps and the streaming buffer now and again not always it would have been nice if they don't lie to their customers and my data expire only next month the 3rd(cause how can they put me from the start of using the data on 2mbps)
