Pathetic service

I have been trying to do number for life on my new contract for the past week now and yet my problem has not been resolved. My number was on contract and its been changed back to pre paid yet the tell me that its still under contract. The logged a query and said it will be sorted in 2-24 hours, for days later my problem i still not resolved. iv been a loyal customer of may years and the level of services and treatment from them is pathetic. Took up a contract for data and so i can wright my exams in peace next week and the matter is not resolved now i need to make other alternatives. im really nont happy so much for saying your the boza network of which your customers are not a priority. I regret taking up this contract with MTN i really regret it!!!
