Not serious about retaining clients

App**** for two of my contracts to be renewed on 10/07/15 - was told phones were on order. 30/07/15 no call from supplier. Went in to supplier and was served by employee with a Vodacom T-shirt? He didn't find my order and placed another order - 2 weeks after that still no call. Sent a complaint to The Executive Complaint Escalations. Got a call and was promised to get back to me by last Friday - no call yet. I had pointed out to them that I had already ported my one number to cell c and was contemplating doing the same - It appears that that does not phase them in the least.
