Very disappointed

Very disappointed with the service and how I paid last month and yet to this day I have not received my data and airtime, I have been reaching out to them via whats app but the only thing I get is that my query has been logged and will get my airtime and data, this was on Monday and even today , still get the same answer . Funny thing is that if they do not get payment within 2 days of the agreed or you pay a little less without doing it on purpose, they block the phone without even contacting the client to check what the problem is , a person could be in hospital or accident and they just block the phone before contacting the client. Every day since 27th October I have been asking about airtime and data.
