Inconsistency

I am very unhappy with Telkom, I have been making payments to their account and emailing it to a lady that I got in touch with when I enquired about my account. Ive sent multiple POP but no response from this person. I've tried contacting Telkom and I can't seem to get ahold of them to confirm if these payments have even been receieiby them. How can I get help seriously..... It's been eons
