Unhappy

Hi, I am writing to express my experience about Telkom. I have a mobile contract with them and they've been debiting my account quite well for the past 7 months, suddenly things changed. They don't debit my account only because they want to charge me the R200 extra for a failed debit order. Last year December they debited R481 yet payment is R289, now in January, they sent me a statement to say I owe them R781, I called to enquire because the money went off my bank account, they told me it's not reflecting. Few days after, my line was suspended and I then transferred R820 as I couldn't live without my phone, guess what they took forever to reconnect my line. I've had it with this company. They have caused me so much of an inconvenience. When I called to enquire about the amount I owe if I want to settle the account, they told me it's R9000, how so? when Samsung galaxy A24 is R4000 and I've been paying for the past 7 months. I wouldn't recommend TELKOM to any of my loved ones, otherwise they will also be diagnosed with anxiety like I was because of the stress they have given me. I couldn't take the stress anymore as I use my number for school purposes.
