Not getting answers on my actual questions

I previously called MTN, about two and a half months back, to cancel my contract, whereby they advised me to call a month before the contract expires (28/07/2015), which I then did, but couldn't get through so I went to an Mtn shop on Monument road in Kempton Park. There the lady told me to come back on 28/07/2015 with my ID book then they will be able to assist me with cancelling the two contacts. I then found out that my debit order (which went up with R20 also) will not be refunded AND there will also be another debit order going off end August. Neither phones will apparently then receive airtime for any of the two debit orders going off because we cancelled the contract 28/07/2015. PLEASE may you clarify on this. Fair enough we didn't pay for the first month as the debit order only went off in the second month as was agreed so I can understand that we forfeit one month's airtime, but why two? Then there's the fact that I was told my airtime would never expire. On 11/08/2015 my R90+ airtime from the previous month was replaced with R10 airtime. I paid for that through the contact and would like it back.
