Totally unsatisfied

I am very unsatisfied and disappointed with the service I have received. Last month in January I paid for a whole months service at R395 and only received internet for two days mind you I work from home so had to pay a different provider so that I don't loose out on work. Last night 4th of February my internet gets turned off again and they tell me I need to pay for February again after I have been promised that I would get credited for January. So now this morning I buy the prepaid option of 10mbps for day at 9am and that still has not been loaded the time now is 12:30. So at this company you just get paying for a service which you don't receive I have all the email threads I have sent them and luckily I also record my calls I would like to find out is there no consumer protection company I can reach out to with my concerns because this is really unacceptable. I nearly lost my job because of their incompetence. Please assist
