bad service

Dear MTN<br> <br> I write this with so much disappointment and dissatisfaction of the Mtn service for the past years. I bought a 24th data using my points but I noticed after few minutes that I couldn't log onto the internet. I switched off and on but the results were still the same. I went to bed hoping I would get my data bundles but nothing of such till this morning. However my worry is that I was billed for something I didn't even make use of. I am highly aware of the challenges you're facing as a company but I would appreciate if this can be solved sooner. I have been an Mtn loyal customer for 10 years now and I really wouldn't want to move to another network.<br> <br> Your prompt response us highly appreciated
