Promotional negligence

Concerning the Home Connecta Flexi, i have used that service since it was introduced. I purchased the 100gig day & 100gig night (R389.00) monthly religiously with an option to rol***** unused data to the next month. Today my bundle (200gig bundle) depleted. I tried to reload another bundle as i usually do & to find out the bundle I usually purchase is no longer there. I called customer service to fine out why is this & to my suprise the operator i spoke to informed me that the bundle i use to purchase was a promotional offer & is no longer available. When i purchased my very first bundle at a cellc store, i was never informed that the 200gig bundle was a promotion and/or it would end. This is the worst of bad service on cellc’s behalf.
