Unhappy

I was debited twice for the month of April when I was told that I was going to be debited early due to the 27th being a holiday I was debited on the 26th and then again on the 28th for the exact same amount On paper I was only supposed to be debited once When I tried to query this I did not get any response from them so I disputed the debit order Today (04\05\2021) I got an sms stating - Mr Singh your debit order on your OM FINANCE loan has been cancelled.Plse reinstate to avoid being handed over for default judgement.Call ***

When I sent an email to the customer service I got a reply stating that they noticed 2 debit orders occuring. The main debit was reversed and that I should reinstate the debit via my bank

There was no apology for the mess up on there end double debiting my account and I am not happy with this whole situation because me being the customer, firstly I shouldn't be debited twice and then second, how am I supposed to know which debit to have reversed???

This issue was on there there end and It should not be rectified by me
