Bad Reception

Glen Eagle estate situated in Glen Erasmia Kempton Park has had a exceptionally bad reception since it was opened 7 years ago. We are building a house and my folks have moved in last year. After having spoken with a few neighbours it became clear that its been an on going problem that falls onto deaf ears. On Friday night we had a emergency situation and the persons involved could not be reaced. If you stand outside then the service indicates good 3G but once you move indoors is goes to no service. This is the same for all the persons I have spoken to and the matter has been at our bodycorporate for years. Apperantly a tower will be placed in the complex but its been said for the last couples of years. I am begging for help, anything accurate information or solutions to the problem as it is a big problem. There is no other communications service, Telkom does not provide a land line. Other service providers like MTN Cell C Iburst and Telkom WiFi has the same problem, no service. Please help us Vodacom?
