Hello my name is ***** ***** I will help you with this.
Yes you do.
If there is evidence it has been paid the Landlord can't call it in. The Landlord must investigate if this is a genuine dispute.
Clearly the bank have provided confirmation - so you have no reason to doubt it was not paid
Can I clarify anything for you about this today please?
Yes. How is not your problem, you have it confirmed by the bank.
Landlord can get their bank to contact the tenant's bank
Does that clarify?
All the best.
