Business Entries - ******** people

We have been ****med into signing the so called contract. Now they are demanding and harassing us into paying R11 958.00 . They **** that they updating details in the directory on behalf of Telkom. After you sign, they send you an invoice via email. They demand payment. Please read the document carefully , and do no sign. After many attempts of calling and harassing me to pay, I told Sandra off, i also screamed at them and put the phone down. I have tried calling them, but i never get through, also it seems that they block incoming emails. They are very shady and do not have ethical business practice . They recently have this lady Fathima calling me , she apparently is from Debit review. she is demanding we pay for the outstanding invoice. I googled Debit review, and cannot find anything, they all ******** people. I told her to send me an official court summons. Do not get scared of them they use harassing tactics to intimidate people into paying .
