GENERAL SERVICE NON-EXISTENT!!

I received an sms from MTN last Tue saying that my roaming service has been successfully added as requested. I tried to phone the call centre immediately as I did not request roaming activation &don't want to be billed for their mistake! The message said there's a high volume of calls &my call got dropped after a few min. I mailed MTN re. the issue on Fri, but have had no response. I tried visiting the MTN shop at Cresta yesterday & they couldn't help me as they were offline. I tried phoning the call centre again this morn &my call got dropped after holding on for 12 min. My husband then tried to phone the call centre on my behalf this morn & had to terminate the call after holding on for 38 min as he had to get back to work. <br> <br> I'm concerned about being billed international rates for my current calls if roaming is activated. I haven't been able to see any details on roaming status when logging in on the website &can't seem to check my status on *111# which I found after a long search on MTN's site for how to check this. I'm also still waiting for feedback after logging a query with the call centre about my contract upgrade on 17 May, which I've tried to follow up on with no luck.
