Update: After re-instating my order, following receiving this complaint, Mazuma proceeded to tell me that my phone was damaged and that it was worth 1/10th what I was offered. Knowing this to be completely false, I asked for it back. After 3 phone call complaints, they eventually returned it over 2 weeks later (after also offering me "£30 of free mazuma goodies" if I changed my review, which I refused), they proceeded to return the wrong phone -- not even a similar one (a cracked iPhone SE rather than a mint Galaxy S7)!! I rang, complained and was promised a call back, what hasn't yet materialised. Still impossible to reach them via phone during most times of the day. Mazuma - kindly return my phone unharmed, or pay me the price we originally agreed; this has been going on for over a month and is is bordering on criminal, hence I will be seeking legal advice if this isn't sorted within 24 hours. Sent phone: Royal Mail marked it as received, but Mazuma did not. They proceeded to tell me that I have taken too long to return my phone via email, attempt to make a phone call to me during the day from an 0345 number (which I couldn't return due to working), didn't leave a message, then immediately cancelled the order for the reason that "the customer couldn't be contacted". The order was then removed from my account and couldn't be queried. I've tried 15 times over 4 days to phone, but the line either rings out or is engaged. Emails also remain unanswered and my phone and payment are nowhere to be found. For this reason, I would recommend flinging your phone into a river over "selling" it to Mazuma as at least this would be a quicker way of losing it.
