Herotel making empty promises

please Mr Herotel help me out with my problem.... January when u guys started promoting Herotel there was promises that states if u install n pole in your yard u get double the line speed for 12 months doesnt matter which speed u take except for 100mb because it goes up max to that, which i did they installed 2 poles and now beginning of may when we got fibre up and running and your prices are R499 for 50mbps the promo that u promised me about double the line speed doesnt count anymore i demand double line speed because that was the agreement
