Telkom mobile

Get poor serves out of them. Struggle a month to speak to the right person to assist me with a bill enquire. Phoned several times on 081 180 to get an email were I can query my account until no one can assist me. Last month there were a debit order that went off my account and this month it is higher then last month and I don't even use the sim card. This morning they send me a demand letter and no where you can quire the problem. Only customer help line and the don't assist you.
