Bad turnaround times and lack of communication and dedication

1 of my debits didn't go off and I had money in my account, I got an sms to pay the account I payed the account of 3.3k and Telkom debited the same amount, I called for a refund the lady said I'll get it within 7 to 10 working days, I got a case number(***2) , when I followed up 9 days later it was said the case number had no info on it I had to open a new case, got a new case number(***6) they said I'll get a refund in 7 to 14 days, when I followed up to see if this case is running and has info they told me they can't refund because there's a lack of evidence I must send a POP but that wasn't communicated through to me at all, in this time goes by and I get a new statement where they already took the Jan amount now I'm in a posative R700,i requested for a team leader to call I am still waiting, I requested to be taken off the debit system they say I must pay 10 before my debit date, they already took my money for Jan but they can't take me off the debit system, they give you the run around and all the turn around times under the sun, imagine waiting 2 days for a team leader to call you
