Shocking beyond words

To say I'm fed up doesn't do my feelings justice. I have been trying since end of January to upgrade online. Last weekend was the 5th time I've done the upgrade online. Previously I never got any acknowledgement or reference to my application. Shockingly this time I got an email with a reference number. I have contacted mtn several times, each time they tell me thay can't pick up my application online. This last time, in this week, same story, even with my reference number. Instead they tell me I must contact the sales team. I asked if they can ask one of the sales team to contact me, all they did was copy and paste the original message and send back to me about contacting the sales team. I have had my contract with mtn for roughly 6 years, and never really had issues. But this is pathetic, and thats putting it lightly. The service, lack of respect and communication is shocking to say the least. I'm a paying customer. But let someone not pay and they are quick to suspend services and demand money owed to them.
