Cell problems

since I open the contract at virgin mobile I had problems with signal on my Samsung s4 mini.<br> I contact virgin mobile lots of times. after a year and half they came back to me and came to test the signal at work.<br> them they said there are good signal and it must be something with the phone.as I told them from the beginning.<br> they came to collect the phone the morning.<br> after a while they told me it will be R3000 for repair.<br> it is under guarantee (not if screen are broken.)<br> but you phone me the morning to tell me you will come and collect that phone and there was nothing wrong with the screen. it are broken and we do not pay<br> <br> NEVER in my live will I do business with virgin mobile again. <br> when my contract expire will seek other contract.<br> worst service ever.<br> worst customer relations ever<br> <br> even they bill me for when I was out of the country and the phone was of.<br> they say I used the phone. I was in Poland<br>
