Mr Delivery deliberate failure of delivery

Currently experiencing a delivery problem with Takealot where items were ordered on 24 April and since then i have received 6 mails that they failed to deliver when i was at the delivery address every time. Phoned several times where new delivery arrangements were made with the call center only to receive a failed delivery mail the following day. on 08/05/2018 a new delivery arrangement was made for today 09/05/2018. This morning i received a mail from takealot that they are returning my items to the warehouse and will not be delivering the order as per the arrangement. Phoned the call center again and was informed that hey will refund(if you are eligible for such credit). and that i can place a new order again but now the item priced increased by almost 30%

Is this normal practice for takealot ?
