8ta with bad service

Oke in april 2015 i hellopetered 8ta for not having signal at my house . They have been at my house twice and saw that the signal is very very bad. After that we got a call telling us we will be geting a booster . Well its 5 months later and still i have to batle to get signal at my house because no booster has been put in yet . Last i heard was 3 weeks ago that they still waiting for sum stuff for the booster . Looks to me by the time i move at my house or my contract ends i will still be waiting for any respons on a booster . Well in 2 months we can upgrade but why will i do that if i cant even use my phone in the comfort of my own house . I have to stand outside to get signal . How bad is that . And we have 2 contracts with them .
