inconvenienced and disorganized by elite mobile

On 2015.12.18 I was sent an sms by Vodacom that my sim-card was sim-swapped. When I phoned Elite Mobile I was told to log a query and that someone would call me. On 2015.12.19 my sim-card was disconnected. I waited for someone at Elite Mobile to contact me, but clearly my query was beneath their time. I called on 2015.12..22 and was told that my account was in arrears. I asked why no one told me this, and was told I had been in June. I went through my messages and I could not find this message from them, but the man insisted it was sent. I asked why a message was not sent during months 2015.06-2015.12 and he could not answer this. So Elite Mobile have cut my line because it would cost them too much decency to SEND ME AN SMS/CALL
