Poor service from the whole Vumatel team

I have been trying since 04/09/2018 to get Vuma out to install a CPE device. I have contacted Nikos, Owen and Kya on various occasions only to be promised that I will be contacted either on the same day or the next by the servicing department to arrange installation. After four attempts I still have not received a call. I live 7-6 Km's from the Bryanston head office and they can't arrange and complete the installation. Poor service all around from Vumatel
