Mid City's customer service is NON-EXISTENT

Mid City's customer service is non-existent! I have not received my water and sanitation account for the month or an SMS reminder with the amount. I have sent 4 e-mails and phoned but received no reply - or a call-back as promised, because the consultant was on the phone with someone else. And now I suppose they are going to charge me interest for their lack of service...
