MTN Internet is non existent or poor

Our phone signal is full bar but the internet service is slow as hell. It always cuts out and then we have to move the phone. It is not like we live in some rural area where there is barely any towers around. We live right next to a ****ing tower and still the internet is slow.it is not the device as we had this problem in multiple devices. overall MTN is actually the worst service provider and not everywhere you go. :/ Seriously considering going to one of the other networks
