Patheric Service from Vodacom and their courier service they use

What a mistake to even think of taking out a contract with Vodacom LOL total joke of a company. my husband got approved for a double deal contract, the phones were sent to the courier company who contacted my husband. Delivery at the time was put as home address but then my husband started working again and we requested that the delivery address be changed. Got an email and sms confirming that the delivery is ready as mentioned my husband requested that delivery be changed to his work address the driver nicely told my husband no problem he will change the address on the sticker when he gets back to the depo, right that was on the 24th June 2020 then on the 26th June we called and nothing has been done about change of address they said that vodacom must change the address and they waiting on a reply, on the 29th June again hubby got a call and again he asked that the delivery address be changed to his work address as they still had the home address on them once again the driver confirmed no problem they will change the sticker immediately at the depo and the next day the phones will be delivered. WOW to our surprise we check on the tracking again and on the 2nd July it states that the package is being sent back to Johannesburg as the delivery was unsuccessful :( WOW what **** service is this and what type of courier company do you use to catch on this nonsense. anyway today is the 14th July no one contacted my husband we called twice after the 2nd July and everytime we told they will call my husband but nothing every since, pathetic service VODACOM i will not recommend anyone to you guys, I hope that the contract account is not going to be billed because I will take this further if it is.
