How can I get a copy of the invoice for the TADO smart thermostat I bought through OVO?
I’ve recently (15/10/2023) Tado smart thermostat from OVO. The bridge unit is faulty, I have discussed with Tado and they will replace the bridge but I need a copy of the invoice as proof of purchase. Lots of searching and email checks I cannot find any invoice. Any help would be appreciated. Thank you. Feeling pretty demoralised as I feel like it is being made deliberately awkward to resolve!
