No answer when phoning, incorrect phone numbers, unprofessional system

You send a SMS to my mother-in-law (first problem) about overdue account (second problem since I did not get a statement or invoice from the institution on who's behalf you request this) and you give a number to call on the SMS which is incorrect (third problem) and when you phone the (assumed to be) correct number found on the internet after half an hour of searching, it also doesn't work (fourth problem) and your Bryanston 011 number also doesn't work (fifth problem). I spent an hour on this now which cost R 610 so maybe you can offset this to the outstanding amount since I'm charging a professional rate for time spent on anything. Please make contact with me urgently.
