worst service providers

I opened a contract couldnt use the tablet the signal on the sim never came, had to go in store do a sim swap to activate it again this could have been solved in store at the time of purchase, as i persued to see if everything was in order. mifi modem on contract the 3 day of use it stoped working.. called in to head office the sim was registered in another persons name. This resulted in me failing to do my assignments signal sucks in any case in kew town area! I had to go in store twice costly.. never recomemnd any1 ever!!!
