FNB allow vendors to ***** you money

OK so I did an international purchase on the internet with my debit card to find that the vendor continued to debit my account. Finding this I requested for this to be sorted and was asked to fill out a Debit dispute form and within 14 days the funds had been reversed, this was last year November. Then in December the vendor debits my account again causing me to have my card changed. Know the chop at the branch who did the card change advised that we not do the debit dispute as yet to ensure. When I returned from a trip in the South African country side I found that there are now two vendors who have debited my account like 18 times. Went to my branch and submitted a debit dispute form and was told 10 - 14 days it will be resolved. 14 days later still nothing, so when I called the call centre I was told that the previous card was not cancelled so nothing was done. fuming I went to my branch and dealt the team leader who apologized on behalf of the chop who did not cancel the old card when providing me with a new one. so I had to re-submit the same dispute, but the team leader then decided that this was ***** an sent it to the ***** department. 14 days later when I called the ***** departments call centre they said that they will not touch it as this in not a ***** case. I had to submit the same dispute to the Debit card Dispute department and this time via the branch manager. Bearing in mind that I not permanently employed and had debit orders bouncing causing me to pawn work tools in order to keep food on the table. Of the 18 Debits the respective department only acknowledged 6 of them and reversed the amounts. To date I am still waiting to hear what is happening with the other amounts and when calling the call centre the chop tells me that there is no debit card dispute department it is the first she hears about this? after screaming the correct number at her and eventually having my call answered. the chop at the Dispute department asked me to hold so she can see whats going on an left me holding for 1 hrs and 45 mins. I hang up and have gone to the branch manager again who also tried calling and was holding for more than 30 min. Now I loose the equipment I was forced to pawn, and have bank charges to deal with due to bounced debit orders. The fact that my bank will let vendors ***** money from my account repeatedly and have the nerve not to keep me posted on their procedures only refunding what they feel like is not acceptable. I will be taking this to court as this means that FNB will allow international vendors to continue debit/taking money from clients accounts even though is supposed to be a once off purchase. Plus the service delivery from some of the FNB agents who don't actually know the departments at the company they work for, is below average or shall I say shocking...... so I will have to loose my equipment to the pawn shop because of having to submit the same thing 3 times over with a 42 day waiting period and hustle to put bread on my table and all that FNB will say is sorry? I will not rest until I get all my money back as the vendors stole from my account. 18 Debits totaling R 7, 900 and was only paid back R 1, 400 .. who is aiding the who? Earl G Davids
