Unhappy customer 😡

I have been with moja prepaid for over 4 years and the customer service level is 0 they are not considerate, I did a debit order payment for 399 and to my surprise it was not debit, I went to their website to set it up again yesterday 399 gone but I’m still not connected, they don’t have a number to call only WhatsApp number the person I was chatting with clearly has no idea what they talking about they not giving clear answers and they have -1 customer service the only thing he/she says they only received the communication today of price increase asked why was I not informed and why did the 399 debit go off, they saying it won’t go through yet it did yesterday, asked if communication was sent out today why must I be affected because I paid yesterday…they don’t know poor customer care the old information is still available online and active yet they say there’s changes 😡
