I have a debt of. £3500 with barclays they have passed it on to mackenzie hall i have tried to negotiate with barclays they refused to deal with me and told me to go to m and h i dont want to go to them as tbey are a bunch of sharks and i dont trust them. Also i have sent them 2 c and d letters which i sent by recorded delivery and i know they got them and they have ignored them and still keep trying to ring and text me and said in a letter they are going to call round to the house am waiting to hear from oft about them. Any advice for me please
