Standard bank home loan:disaster poor service

I have a home loan (bond )with standard bank,i never recieved any sms congratulating me for the house nor a happy letter, I then asked the owner that may I move in(we had an agreement) and he wanted me to pay rent.then later that month standard called and told me my account is in arrears..I was surprised as to how come because they never even told me that I should move in.eacg day since june a more than 5 debt collectors call me...everday I must expalin this story but they alwys say that the calls r recorded.No one is willing to help even the debt clear cwntre (whome I left an email for last week) they just lie and say they called me ..thrre was no redponse.today I tried to call the home loan department as they never debited again this month...they dnt answer my airtime is beinv waisted its now the 6th.when you call them each time you find a new person...poor service!the house is not in good condition but they said that they checked with the engineer.
