RUDE, VERBALLY AGGRESSIVE, NOT LISTENING

So firstly Finchoice is harassing my husband (who does not have the time nor the patience to speak to them) on a DAILY basis 12 x per day. he works in a high sound environment where no phones is even allowed, then when they do phone (afterhours) and I answer (he is driving or ASLEEP) they tend to scream, shout and verbally abuse me. Who do this Call centre agents think they are!!!! oh and then afterwards they through the phone down in my ear. <br> <br> We had an account at Finchoice that was CLOSED in October. Hubby phoned to request a settlement letter, apparently they ''don't send'' those and the guy gave us a settlement amount, we drove to FNB did the payment to the cent, faxed it through to close the account and a month afterwards they phone us and say hey sorry it was the wrong amount given to you please go and pay R300. ***!!!!! <br> <br> We requested the recorded phone call where the amount was given and so nice for them as ''not all calls are recorded'' do they pick and choose which ones are and which aren't? <br> <br> We (me and my husband who is married in COP) has decided that they can now please sue us for it as Finchoice is wrong and verbally abusive then we will also take legal action
