Very bad communication

Since April, I have been waiting for confirmation of a credit that I am due for some goods I returned. I cannot believe it can take 3 months to let me have a statement or an email. I have written many times but still no luck. Phoning is impossible and sending a WhatsApp is also pretty unsatisfying. Think these guys had better shape up with the takeover of Yuppy Chef. At least they were far more professional.
