Beware of mweb

We cancelled the account last month because of bad attitude ,when we wanted too upgrade the account, then suddenly no signal and the line being throttled which has never happened before, when phoning to query why we are told because we used 70 gig of data. This is almost impossible unless you are downloading movies or something every day, is this because we cancelled the account , this is a total ******* and lets see if carte blanche can investigate their own companies or find an excuse to avoid, disgusting service . on querying this with different stores they say in that month if 70 gb is exceeded and yet we are in a new month VERY STRANGE wouldn't you say
