Vodacon VS RAM Couriers-worst service

I have went into 4U Vodashop a few times as well as contacted them as the lady who assisted me would have come back to me with upgrade deals and a few weeks later -still no response. Then in the week of 8 April i have received a call from the Online Upgrade department @ Vodacom online and spoke to a lady called Pravashnee* On Friday 12.04.2019 we have done the upgrade for myself and my Husband. She explained that we would have the devices by Monday or by Tuesday @the latest. As no device was received i contacted them on Wednesday 17 April 2019 and explained we have not yet received the devices. Pravashnee* said that we will have the devices by Thursday COB. I told her that we will be leaving the offices early and she said she will make the arrangements that the devises be delivered @ home should this be after 10AM. The following week Friday(26.04.2019) i have contacted the call Centre again and spoke to Pravashee* as well as Pricilla* as well as Martin* the Manager. Pravashee* explained she did not call or follow up as she thought we are on leave and will not be able to get hold of us. Well if you don't call you wont know would you? Then she said yes but she couldn't as she was in Training. I requested to speak to a Manager where i spoke to Martin* He explained that RAM couriers had the incorrect cellphone nr for deliveries and therefore the device was sent back to Vodacom. ( as per discussion with RAM the previous day with my husband). Martin* the apologized after i have explained that the Contract is between Vodacom and Ram and not Ram and myself but Vodacom and me. because they tried to shift the problem from Vodacom to RAM. Martin* said they will arrange with RAM for the devise to be delivered the following week while we were on Holiday and they will contact me to follow up and with updates. My Husband followed up with RAM almost daily and the device was not yet received by RAM from Vodacom on Thursday 02.05.2019 which would have been the delivery date as per the telephonic discussion with the manager Martin himself. I have contacted the contact centre again on Thursday 02.05.2019 and spoke to Pricilla* where i requested to speak to Martin, and she asked to hold on as she will call him. Then after a few minutes i have been told he is unavailable and in a meeting- Strange he was available before he heard it was me on the line. Pricillia* said she will follow up and come back to me be fore COB. That did not happen. My husband has been following up with RAM, and the devise was received and would have been delivered Thursday 09.05.2019. However again they had the Incorrect contact Number and the device was not delivered. Upon contacting the contact Centre again and 1st spoke Nompundo* i have requested to speak to Martin* and she requested me to hold on. I then spoke to Pricilla* who rudely interrupted me the whole time said that Martin is unavailable as well as Pravashnee* She said that my husband had made arrangements with RAM this morning for delivery tomorrow as they has the incorrect nr. I said, yes i am aware however we were following up and we needed to take the matter in own hands. As Vodacom Upgrade division would have followed up and provided us with feedback this was not done and we needed to make arrangements ourselves. As up to now the devise has not yet been received and no call has been received from Vodacom also. A Upgrade that should have taken 1-2 days are sitting on a 4 week mark - well done Vodacom. I am still struggling to sort out an account of a year ago where my phone did automatic system upgrades without my permission, however Vodacom took their money and never resolved
