Poor customer service

Well makros customer service is the worst so my Dad has an account with the on the 27th of November we went to Makro Wonderboom my Dad is semi deaf so I accompany him most of the time cause he can't hear properly we got to the Makro customer service my Dad wanted to close his account I paid it off I think a month before so I dnt have proof of payment but the statement shows there was a payment done ok so we waiting over an hour to get a response from there customer service which was irritating and time consuming when the eventually picked up they told my dad he can't close the account cause there is an extra amount of R600 and something so the lady gave us an email address to send bank statement and ID only to find out it's a wrong email address another time consuming factor I then e-mailed Makro customer care for more than 3 times no reply I called customer service the first time I was on hold for about 20 Min another time and money consuming factor I finally spoke to someone who gave me an email address to ********** so I emailed them those documents yet it took more than 3 days to get a reply they requested proof then I informed them we don't have the proof of payment the can check on there system I even specificed were I paid and then am told to go to Centurion Makro n request proof which is totally not acceptable I have wasted my time and Money already and yet my dad was not assisted why can't they request for that proof there service is pathetic am disappointed with this service
