lack of service from best home electric moselbay

i got a proline tab and phone with them in 2015 . realise a problem in may 2016 . took in to the branch , to log a problem with tab . I was told to bring in tab and phone . .. after a few months I haven't heard any response . I was just called for payments not feedback on my items . due to so many problems and the same story I explain my self . after almost 9 months they got back to me they have send the items to repairs . they also wasn't sure what the problem might be they were waiting for my guarantee to expired log 2 complaints with head office . still not any solutions.. now they paid 300r to fix a problem on both items . after 9 months . I was told its time to bring my account up to date . after suggestions what the problem might be on the items I cant pay for something I haven't use for 9 months . The service I got from them is to bad the items haven't had any bigger problem just the software . I am not gonna pay any account that is in arrears regards the lack of the service I got from the store / branch . I just don't know what to do anymore .
