Overselling Satellite Bandwidth?

My 2 independent packages are Max Unlimited 10 - I should get up to 10mbps download speeds. 6 Mar - I email advising my average speed on both setups are down between 1.5 to 1.6. Andrew Foulkes responds asking what times it is slow. I advise ALL the time. No word back from Paratus. 10 Mar I ask again. No response. 11 Mar I ask again. Andrew answers that he is speaking to network team. Then makes a “change” that makes it even slower. No word after I tell him. 12 Mar I get a one liner asking me if I can get into my bank and other apps. I advise it is still too slow and everything times out. 13 Mar - nothing from Paratus. I ask again. Liza Kluever asks Schalk Coetzee to check. Schalk advises me that my speeds are “well within the contracted speeds of a Broad Band Fair Share Service”. I contradict this Fair Service but get no response. 14 Mar I ask again. Today is 15 Mar - 9 days later. Deathly quiet in the Paratus office. Still paying for a 10mbps package and getting a 0.7mbps service. STAY AWAY from Paratus. I think they oversell their bandwidth and after sales service is non-existent!
