Amobia really gives no solution to connectivity problems!

I have had such a terrible time with Amobia Communications recently. Since Wednesday 12 November until today 17 November I have had unreliable connectivity. This to the extent that my daughter, who is writing online exams, has missed 2 of her exams and then Monday 16 and today, she had to go to a friend with a constant and reliable service. How is this possible? I also need the internet for business which I haven't been able to do since Wednesday. Since Wednesday I have phoned them, complained, asked for help, begged for help, asked, again and again for a letter to the examiners so my daughter can have a rewrite. I have dealt with respectful people but no alternative or solution to the problem but 'they can't help now'. I recently upgraded to a 15/5 and the monthly fees jumped by R600.00. I received a letter informing me that I must pay.....even though I have been alerting them each and every day, several times a day, that's there's a serious problem with connectivity. I've lost money, had to spend a whole lot more on petrol driving to other places where I could get connectivity, phone calls, not to mention the frustration at 'we're sorry mam"!!!!!!!! How does this work? Who do I speak to? I One thing is for sure, the departments at Amobia do not communicate with each other. I am sooooo disappointed in this company. I am very angry and so tired of their inability to sort my problem out. There are so many other companies out there who provide a better service. Celeste
