Pathetic service and terrible attitube by manager

I am a Telkom customer for the past 4 years.I went to the bluff store to query my data contract as it had expired end November 2015 and was upgraded without any notification to me or consent of mine.Manager asked me to go home and get my ID book which I did.When I got back to the store he now asks for 1 month bank statement,payslip and proof of address as well as filling out a new application yet I am an existing client.I asked him why did he not ask me this in the first place and why do I need to fill a new application to which he became very aggressive and told me that if I don't want to do what he asks then I can cancel my contract.He went as far as to take out a cancellation form and mark the areas that needed to be filled in.while this was transpiring,another customer came in with a similar problem and this time Jose started pushing a chair around and threatened to assault the customer.I advised the customer to lay a complaint and request the footage as the store has cameras to which Jose rep**** we can do what we want as he does not care.He then screamed at the customer and his wife and asked them to get out of the shop.Is this the caliber of Telkom's so called \managers"????"""
