Bad attitude and not helpful

I paid my account on 28 Jan and to 15 Feb payment has not been allocated. Payment was made on RCS self service payment portal. I got an authorization number from my bank. Called RCS for 2 weeks and nobody in call centre can resolve. Escalated to team leader who promises to call everyday and never does. Worst service ever. Funny how when you make a payment on a company's portal they cant find the funds conveniently. Promises to reverse extra charges have not been reversed either. At a totall loss for words...
