Worst client service experience ever 😡

I'm having a serious problem with this company. I am their client, month in, month out we experience problems regarding debit orders. In June they did not debit our accounts so the way they requested us to pay manually it was like it's our fault. The following month I instructed their consultant to debit me for June and July fine that was arranged. Then came milicent and told me that I will need to do a manual payment for June and I went on and did that come debit day to my surprise I was debited for June and July the lady I gave a heads up I think it's Rafia she rescued Milicent and resolved everything and I was refunded. In July everything was sorted. Then came August another cycle of debit drama fine debit orders went through now the debit order is not reflecting on their side I ask them, how? They tell me that they should change their debit order system they apologize etc. They request that I send proof that the debit order went through as in a bank statement to their email address I did that two days ago and guess what? No acknowledgement of receiving the letter nothing, let me tell you to this day my debit order is not reflecting and the debit went through on the 25th of July even after sending proof that the debit order went through which is not my duty at all to do. Yesterday I spoke to them via their whatsapp I was chatting to Xolile at first they said they were difficulties with their debit order system then Xolile says to it takes 7 days for the debit order to reflect. I tell her that's not true you guys are having issues with the debit orders and then she apologized etc. Afterwards, a few seconds later I tell her what was required of me to do in order for my account to be updated I tell I did the day before why haven't you guys updated the account? Guess what and hour later I received a message saying the chat has been closed I rep**** and said no Xolile. I received a response saying my text was sent after hours. I was shocked, ****ed and surprised. All round pathetic service.
