New level of incompetence

Incompetence like you cannot believe. Long story short, within the space of 2,5 years my original line speed was discontinued, automatically upgrading me at an increased cost. 2 months ago, we were hit with yet another above inflation price increase, but the original line speed was made available again. As a pensioner that does not need the 50/50 line speed, I immediately opted for the downgrade again. Despite the advertised line speed, my request for downgrade was met with a "will only become available 1 June", forcing me to pay one month increased premium. Multiple emails later I at last got confirmation that the downgrade was "approved", followed by new contracts, etc, etc. Despite all of this, I received an invoice for the higher line speed / price for the month of June. More emails and telecons later I was promised a new, corrected invoice. Needless to say, my service was downgraded yesterday, but last night the higher amount went off my bank account. Trying to follow up today was a waste of time as no one bothered to respond to my communications. Needless to say, we will be seekign alternative service providers as a matter of priority.
