Bad quality

I have this phone I'm in love with that I purchased from cell c and since the phone arrived it has downloaded only few apps (3apps to be exact) and I can't download other apps. Ive mentioned this to them and they gave me the settings but it didn't help anyway. I complained and the phone was taken for repairs. Mind you the phone, Ive just received it on November. So the phone came back on the 20th of this month from the repairs since it was taken from me on the 5th of this month. OK. After that no body cared to explain what were the findings since I had this problem of can't downloading other apps. It came back with the papers I don't even understand and it only says "tested and passed" if what is it that they were testing I don't know. OK I received the phone back and it did the same problem and since it's a contract phone the debit order went through on the 15th but I can't download the most important applications in the phone. The ones I need the most. I can't even open attachments on my emails because I can't even download pdf. I was hoping when they took the phone they would have called me and asked me what the problem was and so I would ask them to download for me the applications I need but no they did not.

I mean I am stuck with this phone that only has whats app and Facebook and that is the least of my problems. As I mentioned before I went to the nearest branch but I only met a guy who had so much attitude and couldn't help me because I ordered the phone online. I'm worried because I am not going to pay for this phone again. I paid for it the time it was with me and the benefits it came out with but not again when I'm not happy with it. No one buys a phone just for whats app and Facebook no. Every time I download it gives me a caption that says " pdf reader can't be downloaded, try again later if the problem continues contact so and so.... What's that when I am supposed to be facing problems like space only not that the app can't be downloaded? I'm so fed up shame (sorry for the language). Can Cell c send their collection company to come and take this phone as I don't need it anymore. I have already their money anyway. Or else they should know that I won't be paying again for it as long as it still continues doing this. And I don't want a phone that will be taken for repairs now and again and comes back the same while I had no phone. So it's either you sell something you're sure it's of good quality or don't sell it anymore. I'm not going to pay R220 for 24 for whats app, Facebook and fnb app shame I'm sorry. I can do that even on those phone that I buy for 400 and they can do a better job than this one. I don't need this one anymore. I mean it
