Continued Service Failure

My Line has been capped for the last two weeks, when I've been religiously paying for an uncapped service plan. I have made use of the WhatsApp service, what a nightmare, every time I'm given a reference but no resolution. I've tried your phone line, after several attempts and after holding the line for ages I was promised our line would be fixed the same day, guess what, still waiting. Internal Ticket: DAH-***0. Is this how you treat paying customers, I've incurred prepaid data costs for 2 weeks straight due to your service failure. Do you know how frustrating it is to have to explain your situation to a new agent everytime and be left to deal with same predicament over and over. No empathy!!!
