Similarly to just about everyone who has posted here, i have had a terrible experience with Mazuma. Something has clearly gone very wrong with this company as I have previously used them with no issues. I sent my Wife's Galaxy S7 Edge to them having been quoted £75. It was in perfect condition - not a scratch. Like new. I got an email from them saying it had "screen burn on a white background". It's just a lie. I rejected their revised offer of £5. I then got another mail saying they could up their offer to £20!! What!!. I rejected again. I now await return of my phone. I think the Office of Fair Trading should be looking at them - crooks.
