poor customer service

im struggling with my bb9720, phone was booked in 3times and exchanged, 2nd phone also same thing,3rd phone received yesterday and took it back today.same problem.<br> all they say is it depends on blackberry and i told them i cant pay every month on time but people cant reach me due to problem phones they supply.i requested several times for new blackberry(not a 9720) or for them to cancel my contract but its still not done.head office in jhb michelle said she will keep me posted ,but only contacted me once??? <br> what do i do next<br> ill advise people to stay away from vodacom if they only except our money but cant deliver good products or quality products and services. <br> at the end of the day ,people take out contracts so work and people can get hold of them,how can you be reached if you get a **** phone?<br> my money is just good enough to pay them but after that im nothing to vodacom.(just saying how i feel)<br>
