MTN is deteriorating will every passing minute

1 on my numbers didnt get Airtime provising on the 21st April when I called the call center the agent told me she cant see the allocation and she said she would log a query. That I think was on the 29.04.2015<br> On the 5.05.2015 I called the call center and was told my requset log sent to another department and that I should follow up today 06.05.2015. when I called today the agent told me that the technicaldepartmentsaid the airtime was allocated. I then asked proof and she then changed the story and said that its because of the carry over that made me lose the airtime, she tried to explain but what sge was saying didn't make sense ask she brought someone to explain who ks short said that my airtime carry over can never be more thatn R1750. <br> <br> This number is used by my husband who told me what before the 21.04.2015 the airtim on the fone was R2100. currently the balance is R2050. So if the agent said the airtimecan never be more than r1720 my conclusion is that this agents dont know what they are doing.<br> <br> Please allocate my number with the correct airtime and every month from now please send me proof that the airtime is correctly allocated to all my 5 numbers.<br> <br> The sooner the better
