how would i go about making the complaint and thank you

Hi i was in debt £26 to Paypal after sending the payment by echeque whilst it was processing i got an email from credit solutions and didn't take any notice of it as the payment was pending but after checking my statement i had been charged £90 for unpaid direct debits from paypal putting my balance to minus then because it went to overdraft i have then been charged £20 for emergency overdraft what should i do now?
