Accounts error - phone suspension

I'm greatly disappointed in the manner which MTN as a service provider treats us. My phone was suspended due to some error on their side, how can a top-up contract be suspended? worse on the very same day they upload my units. since 9am I've been trying to contact their call centre or customer care but no one picks up and the call will be cut off.<br> <br> what happened to keeping customers happy, this is not the first time it occurred and I hate the fact that I still have another 18 months to continue before I end all ties with MTN due to their poor service. why is there no one taking responsibility? I'm not happy at all with their service, its been 2 days now and no response. <br> <br> why should their strike affect us and why don't the fix their systems because the last time I had to go back to my branch where I did my upgrade, luckily they had a reference numb to the issue which MTN claim they didn't have a clue of, even now the Sabie branch tried contacting them but with no luck. What has their service come to, is this the way to conduct business as broad network service provider. I'm gatvol with this issue, how can I end my contract prematurely so I can get a better service elsewhere.
