Standard Bank - poor customer service

Will not go into details on the forum. My cheque account was handed over to debt collectors. However, when enquiring as to why the account was handed over, even though I physically visited the bank they could not provide any further details. So I now have two different attorneys contacting me for the same account. Namely, LGR Incorporated and Shackleton Credit. I have received two very different reference numbers. I receive two very different statement every month. So now I am at a loss of who I am paying the actual funds too. Kindly note, that I had a bond with Standard Bank and never, in over 8 years, did not meet my obligations. This is poor service. I offered to pay more than the settlement figure, but the staff did not seem interested. So to whom I am actually paying the settlement figure? If this is loyalty it is very poorly received.
