No Data and SMS bundles

I took out a contract on the 1st of May 2015. Up until now I have never received my allocation of Data and SMS bundles. The contract comes with 200 minutes + 500mb data and 200sms. I was given the minutes without a problem. I have sent an email every day to the following address and gone into the store at Nicolway twice. I have tried twitter but no one has bothered to assist me with my query. I have set a 100 rand limit on my account to make sure I don't get a huge bill come the end of the month. I received a sms stating I had nearly reached my 100 rand limit and I know this is from data and sms I have been using. I still have plenty of minutes available to me. My concern here is I have sent an email every day for the past 2 weeks and no one has helped me or even contacted me. I am now being charged for data and sms I should receive every month. If I do receive my allocation now in June there will be nothing carried over from the previous month. Please can someone from MTN assist me.
