Hifi corp does not have ANY client service!!!

I have placed an order with them, NEVER EVER in life have I received this level of service! It’s disgusting, no email feedback, call centre is a mess and I’m still waiting for my parcel after 6 working days! I requested a refund and apart from queries having a 3 working day SLA, a refund has a 7-14 day SLA! What a joke! Certainly my 1st and last order from them, EVER!!!! 100 calls and more than 7 emails!
