Poor service by Edgars

Due to the Public holiday on 1 May, Edgars had issues with banks regarding eft's & debit orders even though the problem eas on there side (i have email confirmation from Edgars on this). I received sms about outstanding dues. I phoned Edgars and told them that I indeed did pay and they confirmed accordingly and apologised. Today, I received a statement and the amount paid in is still showing as outstanding, and they added interest. I phoned Edgars again today and apparently the funds are not paid & thus interest. When I indicated that they had a problem, then the person indicated all's in order. I requested to speak to the team leader as I get conflicting messages, the caller ended the call. So much for customer service
