Was excited to see otrium return to UK but now I'm £200 waiting for a non-existent refund and with no response on email, a chat bot that seems to be permanently offline and only an international phone number. Avoid at all costs and save your money if you're in UK.
Update - otrium did email, said they had refunded, but 5 days later no refund has come through. Not sure what is going on with otrium but not acceptable to be waiting over 4 weeks for a refund.
Further update: this gets progressively worse, they're now trying to defraud me by only refunding the lowest value item in the order which I didn't return, valued at £30, and holding on to the £186 they still owe me for the three items I did return and they previously confirmed receipt of. Avoid at all costs.
