Illicit transactions on account.

1 Months ago I asked about information for a payment holiday on my Vehicle finance as we were expecting a reduction in salary for the time being. This month I check my statement, which shows that my contract period has been extended for 3 months. This I guess means that there is a payment holiday on my account, which I did not approve. Ontop of this there is an R11,200.00 interest added to my account back dated to March 2020, which means there are charging interest on a principle amount dated BEFORE April & May debit orders. (I do see that there were no debit order for June). Obviously non of this can be sorted out, as there is NO answer at customer care, nor does the email address they provide work: ***. I believe that the above mentioned is *******, as no-one contacted me with regards to the query I made, nor did anyone tell me about the options I had. The query was for a one month period for the amount of R5,500.00, which means the interest is more that the extension period. Standard Bank, please get back to me by the close of business tomorrow, 19 June 2020. Otherwise I will have to take you to the Ombusman.
