Could client service or experience get any worse?

After notifying Cell C of my relocation, to another unit within the same complex, and request to move my line a week in advance, along with daily phone calls at cost to escalate the matter, I only received a job ref # eight days later. More phone calls and ELEVEN days later they tell me I'll have to double my subscription as a "new" client if I want the same package on my new line, which is on the identical network (Vuma) and 30m from my old line? Opportunism! Meanwhile they've been charging me for a service I haven't been receiving in March. They blame their shockingly bad efficiency on industrial action, but clients weren't notified, nor were contingency plans initiated.
