Lack of service and communication

I order shoes during the lockdown. It was delivered when we were and currently on level 4. I received 3 orders. I've been emailing Zando since then have received 0 response. Zando lack of response is pathetic and the lockdown has nothing to do with it. They are by far not the cheapest either but consumers support them yet they cannot respond amidst them saying they will. Pathetic service irrespective of lockdown because this is the norm with them.
