No one can do their job properly

All i would like to do is voice my utter frustration with this company!!! I queried my account as one month they take more than what my contract stipulates and then the next month it would be back to normal.i phoned and they fixed the problem. I phoned them to follow up about what will happen next with the money they owe me,the lady informed me that i have two of options, to credit my account where i dont pay my account next month or i can have it refunded. i asked to be refunded which they said they can do for me. i received an sms with a ref number and a few days later it was "resolved" i then phoned and they said it has been approved and will take about 7days to be paid into my account. something told me to phone back and i spoke to another call agent which told me that the amount has been sent to my bank but didn't receive anything,so she sent an email to the account department where a sum of R805.00 will be paid into my account hopefully by the end of the day and a phone call which i received none!i phoned back today the 22/02/2018 to followup once again. i was informed that they took partial of the R805.00 To pay my new fees for february and there is an amount of R300.00 And something credit on my account. by this time i am furious because int the beginning of the month i queried for it to be refunded into my account and just a few days ago the 20/02/2018 they told me that the amount to be refunded is 805.00!!!! Just to show what is the point of me phoning in constantly and following up they do not listen what you have to say or do not care or listen to your query..People need to start listening and put their clients needs first.. if they dare take my premium off for February i'm really going to loose my cool. and i demand that the money which i felt is actually ****** from me to be paid immediatly into my account which i have again phoned for the balanced to refunded
