I have used the butchers shop on numerous occasions and can only state the service from father and son has been excellent, a reason why I and my partner return there time and time again. The father and son Eddie will go out of his way to assist and even pointed out a cheaper alternative on a product when in there last and carries the shopping out to our car for my then pregnant partner and they are plain sociable and welcoming people as you have said also of past experience (I have never used a card to pay there), so I am reading this thread with utter astonishment to the situation you find yourself in. My question to you though is why if you have approached the bank and the shop direct to try and address this have you not gone to the police, rather than posting this, no where have you said father and son have stated they will sort it rather that they have referred you back to the bank. It doesn't matter what country you are in if a person deliberatley holds onto someone elses property with the intention of not returning it this is 'theft' in this case it is alledged fraudulent deception which is obviously criminal and therefore should be addressed by the police authorities. You state this has gone on for months now and clearly issues have escalated. I would hope that this was a genuine error, but you sound/state as if this isn't and therefore question why the police have not been involved already, if it is a genuine error surely the authorities can address it on your behalf for resolution, then when it is addressed you could have put your experience down in the good and bad shop section rather than petition for a ban on shopping at this store as part of your solution solving to the situation. Don't get me wrong I would be very peed off to but I would try and sort it out especially if it starts escalating seeking authority intervention to achieve this. I hope this is resolved quickly for you both but do urge you to address this through the relevant channels.
