Telkom can not deliver to the elderly!

I had issues with Telkom that lasted for over a year and was partly "resolved" for about 2 months I received a "hand-over" notification of none payment and when I submitted my receipts (2 month process) they discovered that I was paying into my "closed account -3 years ago which they provided me with (I lost alot but turned and moved on). I paid re-connection, etc. their fault (they love you to pay but take months to deliver) However, I have access to a working phone, internet and patients. However, my 68 year old mom who lives alone does not and re**** on to call us when she needs assistance. Telkom can not resolve her issues which is running for slightly longer than a year and yet Telkom's billing is so prompt with billing irrespective of it being active or not. Telkom has no service ethics nor staff that resolve issues, unlike their profitable billing department. after numerous complaints of cross lines & calls charged for while she was staying with us but no one can resolve this????
