What a disgrace !!!!!!!!!!!

Disconnected today (public holiday) with no prior notification. I have a account dispute lodged with MTN and a number of e-mails informing me that my dispute is being investigated. So, they just decide to cut me off without asking me to pay. MTN outlets closed, help line useless but they have the ability to disconnect clients. What a disgrace !!!!!!!!!!!!! I've paid the measly amount but no doubt it'll take days for me to be reconnected ??????
