Review Melcom head office

I have been in melcom sunyani branch but this current Manger there is the bad Manger I have meet there. Also when you want there. He don't have respect for customer. Pls melcom Ghana try to advise him. He is the worse Manger there. If your customer and you buy something and you have problems. They way he reacting to you is not fear. He shout customer like his children. He is very disrespectful manger. I want there to buy my things and I forgot my melcom card at home but I have everything on my phone including my ID card but the way this man shout on me. I regret to come to melcom for shopping again. Pls advice him. He is the worse manger I saw in sunyani melcom branches. Thank you very much.
