Poor, pathetic and disgusting service

Every month my debit order goes off on the 1st. So knowingly that 01/01/2020 is a public holiday I made a manual payment at the promenade branch on 31/12/2019. On 08/01/2020 I received my statement via email confirming my payment. On that very same statement my total due for 03/02/2020 was - R1. 02. Even with this I made sure that my monthly subscription fees was in my account. Only to receive an sms on 07/02/2020 to say my debit order bounced as vodacom tried to debit a higher amount. When I called the call center and spoke to Keabetwe and queried my account she then firstly told me that I'm not supposed to pay, then she can't explain to me as to why I received a statement with a credit for my debit order in Feb 2020 and according to her this statement is not on their system but all other statements are. As I'm querying my Jan 2020 statement she starts speaking about Feb payment which is only due at the end of the month. I am so highly ****ed off that I said on that call that I am going to sue vodacom for all the emotional trauma that their consultants put you through and for an error made by vodacom. So I would like to be contacted by a superior regarding this situation and I want a resolution as they now threaten that my line will be locked and I have a business to run and need my number open.
