NO CONSULTANT AT MTN!

I've been trying to speak to a consultant at MTN all morning, but when I dial 135 I get no option to speak with a consultant! I googled this problem and see that an option would be to dial 135 and then 0 - but still it does not give me the option of speaking with someone! Annoyed, I tried to contact a MTN store but not a single store answered my call. I need to speak to someone ASAP regarding my account as your online system is not generating accurate invoices, and you have suspended my services as a result.
