Yoco customer suport stinks

On 28th May had a problem with payment reflected incorrectly/system problem, reported through the Customer Service email system, and sent an ID and asked for more information that was supp****, as *** reports "This number does not exist". On Tuesday 2nd June requested the matter to looked at urgently as it could have been a ********** transaction and I have not received any feedback. On 3rd June a friend approached the Advocate Team who now issued a case number and said they would into why no action has been taken. To date (4th June) I not had any communication from Yoco and am out of pocket due to this blatant lack of customer support. Yes I am a trader and a customer of Yoco. James Heller is my name.
