Bad customer service by Vodacom

Earlier this month I took cellphone contract with Vodacom online. Two days I received a call from to do a confirmation. of the contract. Due to the June 16 holiday the delivery if the cellphone was set on the week between from 17 to 21 June. However no device was delivered instead I received an email from Vodacom courier who told me they are unable to reach me on my number. The number indicated was wrong. This was surprising since the confirmation call had with me I had given correct information which included my physical address. A day later the courier write again asking for my physical address. I wrote them back my correct physical address. No delivery was done which prompted me to phone Vodacom. Vodacom Online told me in fact on their system there was no physical address or cellphone number. This was now on 24 June . The agent took down my details and promised the courier will call me I still have been called. No follow ups are done by Vodacom online. I am really disappointed about the poor level of customer service
