MWeb or Telkom,

I recently decided to re look at my ISP and decided to go the Telkom route as they seem to be substantially cheaper than Mweb. Gave notice to Mweb, on the 16th of Sep, they insisted on a calendar month notice period and agreed to terminate my services on 31 Oct. In order to ensure that I am not without a provider I went to Telkom (Menlyn) to arrange for my new service. Telkom informed me that Mweb must first 'give the line back', so I called Mweb's call center and requested them to assist. The person I spoke to promised me he will do so immediately. After waiting the rest of the day for this to happen I eventually decdided to wait until I can see from my line that Mweb cancelled the service. This happened on 31 Oct. Today 2 Nov I again stood patiently in Telkom's que, to be told after the wait that Mweb has still not 'given the number back', went to Mweb in the same centre who told my they did give the number back, now who is to believe? Why is Telkom (who's line it is) unable to speak to Mweb to sort it out? Why must the customer suffer?
