Disgusting service

I logged cancellation with telkom to cancel my R299 contract 3 weeks ago already. I asked Xoliswa Thabethe to ask her manager to call me with regards to this query since she couldn't assist. She deliberately ignored my emails, 2 of them. I have had to block my debits twice. This affects my credit rating, I need to be reimbursed my reversal fees charged by the bank as well, I just dont know how you will fix my credit score since its dented by your malicious intent to ignore my calls. This is utterly shocking service on your part. I want this sorted out asap.
