Awaiting delivery of external antenna

My complaint is ongoing with Neotel.<br> <br> On 24/8/15 Neotel contacted me and arranged for somebody to come and verify the problem. <br> <br> Then on 26/8/15 a technician from Neotel did some tests with his own equipment and confirmed that I do have a weak modem signal resulting in slow Internet speed. <br> <br> The technician then forwarded an Email to Neotel offices requesting an external antenna. The technician also promised that somebody from Neotel will contact me before Friday 28/8/15 to arrange the delivery and installation of an external antenna, up to now 7/9/15 nobody from Neotel has contacted me.<br> <br> What more do Neotel require before I can expect to get a proper internet speed???<br> <br> <br> Thank You. <br> <br> G D Mostert<br>
