Wrong contract/data allocation

I am currently on a my choice package 100 with MTN of which I receive 100 MTN minutes, 200 sms' and 300MB of data. <br> I receive this monthly on the 21st. <br> This month (July) I received 100 minutes and 500 sms'. I made continuous attempts to contact the call centre of which the call kept cuttin off. At 3pm today (24 July 2015) I finally managed to get through. <br> Explaining my problem and the allocations that weren't made to my contract. I was told by the consultant it usually takes up to 2 - 24 hours (noting I lodged at complaint yesterday at 2pm) so it's already been 24 hours. If not I would just have to wait 3 working days because they have a back log and the strike caused issues. <br> Firstly all of those have nothing to do with me. <br> I am now 3 days over due on my data allocation from them. I then escalated the call I spoke to a girl Emma Lee (I stand under correction) who then told me they need to fix this once and for all but she can take the 300 sms' extra that I received away from my network in the mean time. In which I told her I felt that, that was totally unfair as they are so easily able to take something away they gave me too much of but its a huge issue to give me whats owing.
