VODACOM DISAPOINTING SERVICE

What a disapointing service Vodacom has supp****. On 8 April was approved for a contract with Vodacom deal being 2 x Samsung A21s. On 9 April receive an sms out of stock, so we contact vodacom to find out what other options there are and was informed by Cindy there is blue available and not black (taking note order was 1 blue and 1 black) Called back again after 12h00 on 9 April (contact in husbands name) spoke to Nombuso whereby we were once again informed only blue available so we changed the phones to both blue, while on the line she changed all info with shipping we confirmed should receive order on Monday or Tuesday. Tuesday 13 April contacted vodacom again and again sasha confirmed blue in stock. Today 14 April husband receives phonecall from vodacom now apparently there is no stock, so how is it possible that our order that was confirmed 3 times being blue phones is now suddenly out of stock. Vodacom service is useless and we will be looking at cancelling this contract before it even begins.
