Bad service and misleading clients

Good Day

i app**** for a contract with you guys for the vodacom tablet in November and your consultantant didnt capture or do the sale properly as i instructed in the call that i would like th debit order date to be the 25th each month ,,,,,,,,,,, but your incompetant agent captured 31st ,,,,,,,,, i do not have notify-me on my account so i was unaware the debit order didnt go off ,,,, then i recieved an sms of arrears from you guys and called your call centre trying to sort this thing out and was told that there are unpaid charges of a 100 for unpaid debot orders now i refuse to pay these charges the agent that didnt do their job right needs to pay them as i refuse ,,,,,,, i have complained before and was told that i would only pay the instalment but recieved my statement and i see the arrears amount was then now added i refuse to pay it ........... your agent is incompetant and unreliable and mislead me and didnt capture or apply listening s****s i suggest you go listen to the sales call as i will not pay for the arrears she did not even mention to me of a payment that will go off in november as i took the contract with her in november and received the phone in November .
