MTN Home LTE - Waste of money / Inconsistent speeds / lags / ZERO client service

I am very disappointed with this new Home LTE product. From the get go I had horrible speeds (paying for the more expensive 35MPS 5G setup) - I would get full speed, a minute later around 1mbps, then nothing, then full speed, then in-between and this all in a 5 minute window. Went back to the store. Apparently the address was wrong (this is complete nonsense). 'Fixed' the address. Exactly the same stories. I have been back 4 times to the store - no difference. And here is the cherry on top. I had to pay for the simcard, pro rata for the 1st month, in full for the second month UPFRONT. I did (not happy), and then MTN went to debit my account AGAIN for a month (and I have already paid this upfront). I have called the call center which refers me back to the store. I have visited the store which tells me they cannot assist - I must cancel and pay the notice month etc. They want me to give a calendar months notice for a service which is horrible - I am not getting what I have paid for and refuses to cancel or refund. This is really shocking MTN. NOT HAPPY AT ALL.
