phone not repaired after being booked twice

Its saddens me to write this cause every month I pay my contract and i expect to get good service but that is not the case<br> <br> <br> I am currently using a virgin mobile contract phone which i bought in 2013. Everything was fine untill last year October when i was experiencing problems with my phone and decided to book it in at east gate and got my phone after 2 weeks thinking it was fixed. To my surprise it was not. A month later i was experiencing same problems i booked in for. <br> <br> <br> This month i decided to book in my phone again at maponya mall for the same problems I had in october after it was fixed and after 2 weeks i got my phone and guess what 4 days later i am experiencing the same problems. <br> <br> Now i am asking myself. Did they really fix my phone or what. How can i experience the same problems twice. This is unacceptable. I am not happy at all. <br> <br> <br> I mean booking in my phone will not only frustrate me but i will be inconvenient to me.
