DAYLIGHT ******S, NEVER USE VODACOM ONLINE SERVICES EVER

I app**** for a contract online huawie p20 lit which is a dual sim phone, when the phone arrived to my surprise i'm told it would never function as a dual sim even though it is because the VODACOM software doesn't allow such , i then called vodacom to ask them to change the contract back to my old no. since it wouldn't function as dual then i was told that it is impossible to do so because the number was already activated, i'm then told to return the fone and cancel contract after three days post collection i wait 2 weeks for the phone to be picked up and then i call after three days am them told it hasn't arrived on their side a month later Vodacom deducts money for the contract for a phone that i don't have, i then call in and am told that i will have to wait 14 working days for my money to be refunded and they will send me details soon as the contract has been cancelled and till today two months later i'm still waiting on response and contract to be cancelled and my money to be refunded....this is unacceptable vodacom!!! it only took one phone call to get the contract why you giving me run arounds???
