Poor service delivery

On 30 October 2017, I took my tablet to The Grove (Vodashop), to gain a quote for repairs. Quote period 1 - 2 days. After 2 days I phoned to enquire about my quote. I was informed that I must phone Potch repairs. I phoned Potch repairs and was informed that they cannot repair my phone as the Grove used the incorrect Job description. My tablet in the meantime is between The Grove Shop and Potch repairs, and nobody has feedback for me. This resulted in I had to purchase a cheap phone in the meanwhile for my son to be able to get in contact with him. I feel this is unfair. I thought that a Vodacom pride themselves on good customer relations. I feel they must repair my tablet on their own expense or hand me a new tablet, but this cannot carry on
