A month of no internet service = Double Billing?!?

This will be my 3rd bad review of Vodacom Fibre in the last 2 months. If you are considering using them as your internet provider- STRONGLY RECONSIDER. Long story short- we moved houses and we requested *a month in advance* to have our Fibre services moved to our new address. This fell on deaf ears. The week of the move we followed up telephonically and they did not even acknoweldge our initial request. We made the request again on the 17th of May, we were contacted shortly thereafter and were told we need to open a new sales order as it will be a new line. We kept following up daily- spent hours on the phone on hold to find out when our service will be activated in our new address. Open Serve has to come and install the line, it was an absolute nightmare to found out when they were coming. At one point they phoned me to tell me they were on their way, but to the wrong address! When I corrected the address, they took another week to show up. I understand this is not Vodacom's issue, but they were the ones who had to schedule them to come, so it took 2 reviews to get these guys to come. It was more than a month later that they showed up, and then ANOTHER 3 days later for the Vodacom technician to connect the router. The best part was, Vodacom sends a technician who is not a SA citizen and did not have a valid work permit- so the security at my estate would not let him in! He showed up without proper ID that he is from Vodacom, with an unmarked vehicle- how is anyone supposed to know this is a valid technician!? Ridiculous. So after all this inconvenience, I find out that Vodacom was so kind to DOUBLE CHARGE ME for the month of June AND July for 2 fibre lines- the old one from our previous house as well as the new house. This is just the cherry on top! I made several calls before month-end saying that they need to please change the billing, that it is completely unfair that after more than a month with NO fibre service, that I am being double billed for June and July for TWO lines?

Can the smooth-talking Vodacom contact person who is going to phone me after this review and tell me "they will resolve this" please use this reference number I am quoting to follow up on this. Please DO NOT tell me that Vodacom was right in billing me twice because "the migration" from the old line to the new line didn't happen, I don't care for your tech-speak nonsense and this is not my problem as the customer. Please CREDIT MY ACCOUNT with the incorrect billed months where I was not using the old line. I will cancel all my Vodacom contracts and take my business elsewhere if this is not resolved. This is the last straw for me.
