Reconnection of contract

Yesterday morning I got a sms saying that i should make a payment for my MTN contract R540.90 immediately into the ABSA bank account but no ref or email to send the proof of payment to. I made a instant payment yesterday via EFT from FNB with a extra R40 transaction fee. I tried to phone the service provider on 808 and 809 but the line keeps cutting off cant get trough to a agent to confirm that they did receive my payment. I got through to the voice promt this morning to get the email address to send the proof of payment to after numerous attempts and could only send the email today. How long must I still wait to be reconnected? Why was there no phone call to remind me to make a payment before suspending my account, last communication I got was on the 05/03/2015 via sms. I am very unhappy as this is my only communication device. <br> <br> I hope to hear from you soon.
