Harrassment of unemployed client

My mum has been unemployed for the last 8 years and does not earn an income. An affidavit advising same was provided to Joseph from Brooks and Luyt but still insists on payments. On good faith my hubby and I have been paying this account for her but my mum received an sms last week to be informed that summons is going to be issued as the amount she is paying is too little. We cannot afford to anymore as we have our own responsibilities as explained to Joseph but he keeps calling every month harassing her for money.<br> This morning I sent another fax including the affidavit and advising that she does not earn an income. Kindly look into this matter as she is a person that does not work and cannot pay this account.<br> <br> Kindly contact me for further information regarding this account.
