Afrihost Ongoing Poor Connectivity

I signed up and bought a mobile ****le from Afrihost around October last year, and use the specified MTN sim card, and Afrihost's airtime..<br> Since then I have had many, many connectivity issues and this has been almost a daily issue whereby I am connected but with no internet access.<br> I have phoned Afrihost many times (they will attest to this fact), took my Huawei ****le to them to get checked (rather casually I must say), and last week they did a master reset which I was told would sort the problem out - all to no avail! This afternoon I have had to reboot my ****le repeatedly and now finally get a connection.<br> <br> This is simply not good enough, I work from home and rely on my internet connection!
