Extremely Unhappy

Being a client for years whether it's an order for delivery or collection I've been let down on 3 occasions now. I thought of reporting this now as for being a paying customer I feel that I should be compensated for extras I buy when not receiving any. First of all, now that I don't order 2 Pizzas I'm told we will make an effort to deliver seeing you buy on a regular basis, really? Did you know that I'm also charged for delivery? Second of all, no apology for charging me for previous extras, only solution is that the person who answered said I will check and make sure everything is on the order. Not giving me a chance to appeal or have any other words said in this single conversation. Do you need the pictures and the slip as proof before I'm able to be treated as a paying customer and to proof my bad experience? I will now support your other branch in my nearby area as I think Zambezi's service is a rating of 1/5. Fyi, the drivers always gives a 100% service and are very friendly. Sad to learn I can't support them for delivering a great service.
