Telkom sending Emoluments, but didn't sort out the account before handing over!

So Telkom messed me around for almost a year with not giving me a credit on my landline when they failed to get my ADSL and Landline right but are now sending me an SMS that my employer is obliged to pay a portion of my salary to the judgement creditor?

Dear Telkom,

Had you guys sorted my line issue when I had one this wouldn't have happened, with the last call we had even with your Blake and Associates people, I was told they will sort the issue of the credit out and send me an email, 2 weeks went and I got no email about this and obviously no credit, and now I get such an sms stated as above saying how much I must pay (which is R6k+) with no further information, I'm sorry sort your non-sense of not providing proper customer service out before sending sms' like that to me.

I have had nothing but utterly poor services from you during my time of being your customer, so please sort this out before you send judgments for something you failed to help me with.
