Problem with an upgrade

I requested for an upgrade since December and made more than 40 calls of which already each call consists of over 20 minutes and been promised that I will be upgraded and I requested for them to have a look into the matter and to get back to me and asked for a manager to return my call and not even 1 call from anyone. I've requested for an upgrade to a 25meg upload and been upgraded to a 40/10 and I was under the impression that the 40 was the upload but it wasn't. The reason for the 25 Meg was so that my wife can work from home as their company has requested for the upload and I've been promised by another agent on the 25 of April that my line will be upgraded on the 26th of April but never materialized. I'm at this point feeling to cancel this line but can't because there's no other services in our area. I don't know how and what do with just getting to an upgrade of 100/50 line which they have told me that I can only do it in 30 days seeing that my line was upgraded on the 15th of April already but wasn't my request and I can't wait for the 15th of May because my wife has to start working from home by this week. I don't know why mweb employ such *********** people which makes empty promises to return my call and not 1 call from mweb. I hope this will be my solution to getting my line up and running on the 100/50 line ASAP.
