Phone calls any time - complete harassment

My account is presently half an instalment in arrears to which arrangements were made if I did not go into ackermans over the weekend I would do an EFT. I would get on average 5 phone calls a day from number ********** 442. When answering the call would be put down. This was discussed with 2 TEAM LEADERS as I did not get satisfaction from the call agents, one of which basically told me I was lying about the calls from your contact centre.

A payment was made via EFT on Saturday. This morning Monday I get a phone call at 06h07am. REALLY? This is absolute harassment. An EFT will only show by Tuesday - even I know that.

To phone someone at 6am in the morning is unacceptable.
