BIS email cancellation

woke up this morning with an email stating my emails account activated on my Blackberry have been deleted. Called the call centre and the consultant over the phone told me my services are active, that she is going to transfer me to RIM technicians. the phone dropped after the transfer. Tried calling again, MTN says I have exceeded my free calling limit to their centre. Went to the west gate mall MTN, there a lady told me my services are active. I asked her to add my emails again, she said I must contact MTN call centre directly. now I am feeling cheated as my subscription is not expired, but my usage is halved. I used emails yesterday. today I can't.this is unfair
