Bad Service

I took delivery of my SIM only data package yesterday in Musgrave Durban (Work Address). Upon testing everything worked at 100%. When I got home, this is what the data deal was taken for, there was no signal. I was unable to connect to the LTE network. Now MWEB works with Cell C for their LTE deals. I did tell the consultant that I moved away from Cell C about 5 years ago due to no coverage. He then checked the coverage map and it showed that I have coverage. However there definitely seems to be an error because I cannot pick up LTE signal.

I called in today to cancel and I am told that I can't as MWEB needs a calender month's notice and technical has to get involved.

This is really unfair as I was sold this product thinking it would work at my home address, it doesn't. I will not pay a month's premium for a service I cannot use!

PLEASE HELP!
