MTN taking AGES to activate the upgrades on my lines!

I called in to cancel my 4 lines(out of 5) as there was no deal that was adequate enough for me. the agent on the phone managed to change my mind and offer me a package that I was happy with. I decided to take it out on all 4 of the contracts that was up for renewal, as he was busy doing the upgrade he mentioned the system is slow and he will capture all the details for all 4 numbers thereafter I will get an SMS confirming the upgrade. he provided me with a reference number and I assumed that all is well. however I walked into the mtn store on Saturday only to find out that there wasnt anything done on any of my numbers, the guy at the store suggested I call the retentions department and check but they only open again on Monday, however, I went home and called, a lady confirmed that there is a note on my profile regarding the upgrade so all should be fine and I should call in on Monday. I called in on monday and the agent said that it will be processed and that i should expect an sms i n2 days, i called in yesterday only for the agen to tell me that it will take upto a week as they waiting for management to release that offer on the system so it can be captured or something of that sort. now my monthly allocation of minutes and data usually gets loaded on the 21st, however for November they moved it to the 16th as it was the last month and the reason that they are improving their services , all bs, now on the 16th all my lines got a fraction of what we usually get and now on the 23rd it was just about exhausted so I was ok with it as I assume I would have my data and minutes by the 24th or so. so now all my lines got no data and its really making my life difficult!
