Vodacom don't care!!!!

One of our phones was due for upgrade on 29 January this year and as we needed to get a Tablet for our daughter for High School we chose to upgrade to a tablet. My husband and I went to the Vodacom shop in Baywest, PE and spoke to Eden, she looked to see if they had any tablets in stock and told us they didn't, that there was a problem getting some makes as there were lots of customers waiting with them on back order but she would look to see what they could get. She found that the Huawei T5 was still available and we put in the order signed papers agreed to the amount to pay etc. She then told us it would be available in 7 working days. She took my number to call when it arrived. 7 working days came and went and we had heard nothing so my husband went back to the Vodacom store and was told our tablet was on back order and that Eden no longer worked at the store. He kept calm as we had explained that we needed it for the 15th February for our daughters return to school and if we had know that there would be a problem we would have made other plans on the 29th January when other stores had tablets available still. My husband insisted that it was their error and that one way or another they must find him a tablet. After lots of running around the manager told us that they had established that there was a Lenovo M10 in stock in Johannesburg and they were checking how quickly they could get it to us, leading us to believe we would get it before she started school. Once again we had to follow up ourselves due to no one getting back to us and they told us Thursday 19/2 was the earliest they could get it. It was not ideal but we put in the order and waited for it to arrive. We heard nothing up until yesterday 19/2 so my husband went to the store again today and was told that the manager we dealt with was on leave and that the tablet we ordered "WAS ON BACK ORDER!!!!!" So for 3 weeks now we have been **** to by Vodacom, still do not have a tablet and no one got back to us when they made promises to. My husband is currently waiting again for someone to contact him. 3 weeks ago we could have made alternative plans and we are currently borrowing a tablet from a family member who will need it returned this weekend. I have been a loyal customer of Vodacom for years now but this has made me furious with the company for their complete lack of customer service. I need the tablet we ordered NOW!!!
