Wrongly upgraded - do not get my data

I am a Nashua Mobile client and have been passed on to MTN service providers to be looked after.<br> <br> Since this move by Nashua Mobile, i have only been upset. I have upgraded (28-07-2015) and have agreed to go for the Sony Xperia Z3 Compact, R399 p/month, 300 MB data, 200 sms's, 100 anytime minutes<br> <br> I received an sms on the 2-07-2015, saying that i have been credited with 300 MINUTES.... where is my 300 MB data? <br> <br> i have tried calling the customer service, only to sit waiting 24 min plus with absolutely no answer. Tried the online contact, this page asked me to fill in my cell phone number, i do this and it gives me an error as if i am not an MTN Client.... then i try dialing MTN service via my MTN APP on my phone.... i get a \the number you have dialed is unavailable"needless to say"
