Worse Service in the History of any body life

I had a worse service with openserve seriously terrible.in April i chance my service with Mweb and they gave me a month which was may for the process so by 31 may my cancelation was finalized and 2nd of june my line was released. In june i begin to apply to webafrica but that took 2 weeks as they couldn't proceed because they said my line was still with another ISP even after sending my cancelation to show that's not true unfortunately that didn't work out.i decided to try supersonic that was june and now its august supersonic came back to saying the same thing am with another ISP,i took it upon myself to email openserve to ask which ISP my BNumber/number belong to they said no one,they told me my line was released in june,they even set up an appointments To activate my line and it was activated with no internet and when i inquire from supersonic i was told my line is with another ISP even after all that trouble, of **** activation and receiving router my line was cancel mid you no one from supersonic called me to explain.i thought let me reapply and after 2 week of being told my order is place successfuly with an FNO again am told by supersonic my line is with another ISP.mid you this FNO is openserve who supposed to help you yet making your life a living hell.really are you people trying to make me crazy,are you so incompitetant that need to be told how to do your jobs,you tell me one thing and do something different. You want a person to email you but never respond,you take weeks to ask stupid questions where a person has explain their story yet you don't read their email properly to respond to what was asked.Wow really openserve is worse,explain to me which ISP am with so that i can fix this myself,stop telling me am with an ISP and not saying the name of the ISP you have that information tell me,unless when Mweb told you to release my line as am nolonger with them you didnt do it that's the only explanation for this ridiculousness mess.
