Verry unhappy

Fiber from hell. Quick to switch off when not paid but to turn back on was an issue. So last night found out after switch on the account again wifi ran at 5mbs and i am paying for a 50 up and down mbs. Technican told me my router is outdated. 7 mounths with pluxnet and in the time it worked 1 mounth good. Thabiso the tech was the only one that is telling me the truth why i am struggeling the hole time with conection issues. So i paid for the mounth but 3weeks now no working wifi. Really upset about this. Then some of the techs at MBV does not have the respect to even anser a massage.
