Poor Fibre Line speeds

I recently had fibre with MTN installed at my residence with a claimed line speed of 75mb download & upload however every speed test done, including one with their agent resulted in 4mb up and 5mb down, nowhere close to what I am paying for. A case was logged with their technical support a week ago and there is still no feedback or change in the poor line speeds. MTN, please contact me to resolve this or have your cancellation team contact me to collect your equipment and I will find a more reliable and competent ISP to take my money and actually provide decent internet!
