NO Internet iro VODACOM

I have been to Vodacom Midlands Mall iro no access to internet a week ago and was informed by a consultant that Vodacom is busy with maintenance on their towers would be finish and restored by 27/1/15. I've had no access for more than 2 weeks and still have the problem which is very frustrating. When I called Customer Care they advised that there is nothing they can do but will log a complaint, but the problem should be restored shortly. I have lost 1.60G data due to the above and I have received an sms from Vodacom to which I feel I've paid for but couldn't use it, which I wasn't at fault and yet paid for the data. I want to know why Vodacom cannot carry it over, for me to use once their maintenance is finalised. I cannot access emails/internet. I am desperate for assistanc and have been referred to you for assistance. I cannot download any work related emails. Your assistance would be appreciated and I look forward to a positive response from Vodacom. Thank you kindly
