Sorting out my account and rude lady

Just before Easter I upgrade my contract with MTN. Anton from Lakeside Mall Benoni explains that I will get 100 minutes, 300 MB data and 200 sms's. On 27 April I received sms from MTN but only the 100 minutes was added to my acc. No data, no sms's. I visit the store immediately. Anton sent an email to CA Service Desk Manager to lock a query. He took a screen shot photo with my phone - and told me it will take 24 hours<br> On 28 April I sent a reminder. to keep me posted on the progress. On 29 April I sent email again. No response to my email. On 6 May I sent email again - no reply. I called several times with no luck to speak to Anton. The lady who answered the phone was very unprofessional. I was holding for about 10 minutes and then they put the phone down. I visited the store again. I was sitting there and left after 30 minute (because it was closing time and still not sorted). I called on 13 May and spoke to Carolyn - she promised to call me the next day. No call... Later that day I received an email from Anton - promise to sent me the \billing Query Reference"the next day. No sms"
